negative · reviewer's own thumbsView post →if a game is published by team17, you can bet itll be forgotten and abandoned shortly after release. this game is no different. abandoned for years, was hoping for a sign of life, but nope. abandoned.
negative · reviewer's own thumbsView post →Why someone just don't buy the rights of this game and develop a Battlebot like game inside of it? I mean, if we have a strong community manager and marketing team working on this game, it could become really HUGE.
positive · reviewer's own thumbsView post →Today we're celebrating Main Assembly - a sandbox game where you get to create fantastical robots and flying contraptions! 🏗️🤖🚀 New to this series? Well, we're highlighting creative & wacky #games from the #gamedev #solodev & #indiegamedev community using our outlier lists
unlabelledView post →Devs disappeared from the face of the earth
negative · reviewer's own thumbsView post →need a network connection just to play alone got halfway through an unsaved build just to be kicked out by laggy wifi also ♥♥♥♥♥♥♥ controls
negative · reviewer's own thumbsView post →no updates for years...
negative · reviewer's own thumbsView post →Was a good game when it was still being developed but has been abandoned since 2021 and the last well worked on thing uploaded to the workshop is from 2021. I hope Bad Yolk Games returns one day to finish the development.
negative · reviewer's own thumbsView post →this game is great, i just wish the devs would update it. plssssss devs the community begs for updates
positive · reviewer's own thumbsView post →It is fun. Unfortunately, the devs brought it out of early access out of laziness. They didn't want to improve it anymore and considered it finished, leaving lots to be desired.
negative · reviewer's own thumbsView post →sh*t. doesn't get updated in 3 years. abandoned
negative · reviewer's own thumbsView post →im too dumb for this game
negative · reviewer's own thumbsView post →Great game and you may be confused why I made this a bad review. Well first off this game has not gotten an new update in forever! On top of that the community is dead with the average players online a day being 20 people. This game has so much potential but its such a dead game. That is why I cannot recommend it. And also them charging $20 for a dead game is ridiculous!
negative · reviewer's own thumbsView post →Such potential but it's sad it died early.
positive · reviewer's own thumbsView post →idk why people are saying it was abandoned its a fully fleshed out game i love it
positive · reviewer's own thumbsView post →Abandoned since 2021
negative · reviewer's own thumbsView post →DO NOT BUY the game has been abandoned due to its devs going bankrupt (rip) in its current state the game is generally very glitchy. Great game ruined by money
negative · reviewer's own thumbsView post →It is pretty fun, but the game is totally dead. no more updates. I wouldn't pick it up unless it was on sale.
negative · reviewer's own thumbsView post →In a world of Creative sandbox games, Main assembly often stands out of the limelight unlike other infamous titles like Scrap mechanic or Trailmakers. Despite being not known by many , MA holds great value. Its a fairly polished game with huge amounts of freedom given to the player. The graphics are cute and bright. the physics are on point and controls really well too. you have campaign mode with narration to keep you going as well as open world with a huge map that has seasons too. Many and…
positive · reviewer's own thumbsView post →so far my 2nd fav game. this game is kinda hard at first and complex but u can figure it out by either yourself or ingame tutorials and if you do not care about how hard the game is like me then this is a perfect game.
positive · reviewer's own thumbsView post →I wrote a review earlier because it literally kept asking me to do one. I've finally had time to "play" and came to the conclusion I regret spending money on this. The body building is super neat, and it has some pretty good deformation physics and all that... But the physics? /The physics.../ Physics are bad. Building is bad. The scripting/coding is bad. Everything beside the literal body building is just awful. I can't even compliment the graphics because every so often there was this filter…
negative · reviewer's own thumbsView post →fun game if you like planes and/or you're smart
positive · reviewer's own thumbsView post →dead game warning. unfortunatly the game hasnt had an update for a while. good game though
positive · reviewer's own thumbsView post →mainly assembled
positive · reviewer's own thumbsView post →Good game but very very very rare updates with new content, also it is hard to even find others playing the game at the same time as you, i have never found another person online except for one time when i tried to join their server and then the game crashed. Otherwise, good game.
negative · reviewer's own thumbsView post →Was a very good game. But no one plays it anymore, and it has yet to be updated in over 4 years. Safe to say it has been abandoned.
positive · reviewer's own thumbsView post →This is a good sandbox game, albeit very limited in terms of the events and in-world NPCs. But for the amount I got it, this was definitely a freaking steal! Play this if you want to flex your creativity and want to build some sort of vehicle. The aerodynamics work and is clunky for a reason (I'd like to believe the devs purposely made it hard to make aircraft because it's hard in real life). But if you're looking for some sort of story or events, I suggest otherwise. Overall, good game.
positive · reviewer's own thumbsView post →Absolutely amazing freaking game! I've had this game in my steam library for about 9 months just waiting until I could get a better computer to play it, I definitely would say the wait was worth it, and I regret not paying full sticker price because I feel guilty for buying it 80 percent off. I've only been playing his game since Friday, and yes, this game takes a bit to understand the controls, and the bits and bobs of this game. I personally do not have all of them down, but it is pretty…
positive · reviewer's own thumbsView post →Unfortunately, game keeps crashing again and again when playing multiplayer, such a potential on this game but abandonated, last update was in 2020, me and my friend really liked when we could play it, but it kept crashing when trying to use Hinges online, to the point were the game started crashing as we hit play on steam, if you play solo then the game might be fun, but other than that is just constant crashing on multiplayer edit: looks like this crash exists since forever, you can avoid…
negative · reviewer's own thumbsView post →Pretty fun, although I will say I was pretty bummed when I found out how bad the aerodynamics system was. You can build rudimentary rockets but if you wanna build a plane you're basically just hiding a rocket under a fake chassis. I will say I like the paneling system, I just wish it was more fluent and less buggy. BTW This game is NOT worth full price. Wait until a sale. I was gifted this for ~$4
positive · reviewer's own thumbsView post →I really want to recommend this because it seems great, but this is yet another game that has screwed up the ability to change keybinds. I play on a razer tartarus so I move with the arrow keys in every game I play and rebinding the movement of the vehicles doesn't work. They are hard bound to wasd, so I can't even get through the second room of the tutorial. I could do some work around magic if I could reset the keybinds to default, but there's no button to do that. Hopefully they fix this,…
negative · reviewer's own thumbsView post →The game in many ways is more enjoyable than Trailmakers. For whatever reason, the other game took off and this one is seemingly abandoned. There are still a lot of bugs in the game, and crashes Hopefully they come back to this project eventually
positive · reviewer's own thumbsView post →Haven't play this for a period This sandbox game equipped a rare way to craft vessels, I call it Build-By-Skin. Build-By-Skin means you can manipulate mesh of blocks, transform it, twist it. The only 2 games I know using this way to build is Main Assembly and Homebrew. Build-By-Skin is more complicate and more flexible than Build-By-Blocks, it allows player spend more time to craft vessels with curvier appearance. As a changing player, I enjoy this a long time ago, but now I prefer some fast…
positive · reviewer's own thumbsView post →This game. I've spent way too long on this game. I know it's only 70 hours, but that's at least 60 hours of my life I will never get back. And you know what? If I could go back, I'd do it again. Because I hate myself. --LONG REVIEW ALERT-- Main Assembly looks more difficult than it is. And don't get me wrong: it can be *super* difficult--but only if you make it that way. It's not like other games where you need a degree in engineering to get your car to go straight--building a functional…
positive · reviewer's own thumbsView post →Cash grab! This game is boring to say the least and the Devs have not touched it since release. Spend your money on something fun like Trailmakers or Terratech.
negative · reviewer's own thumbsView post →Interesting, but fairly bare-bones. Abandoned right after release. Might be worth a few hours on a heavy discount, but don't expect much more than that.
negative · reviewer's own thumbsView post →it is abandoned, need i say more?
negative · reviewer's own thumbsView post →Main Assembly gives creative players a robust set of tools to build and experiment with robots, provided they have the patience to learn its systems through trial and error due to a very limited tutorial.
positive · reviewer's own thumbsView post →great engineering game, more complex side though provides alot more freedom with what you can do. If your intrested in engineering, design, or anything related to this i highly suggest you consider getting this game. The controls/UI are a bit odd to use, but not hard to get used to. Some of the rigid 3D parts (like suspension and wheels) feel somewhat lacking in their ability to visually or physically change which can cause things like suspension to stick out of surfaces so they work or…
positive · reviewer's own thumbsView post →Insanely fun game for a while, tons of cool mechanics and such, but sadly was just abandoned without proper mod support, or any new, meaningful additions, I truly hope the devs somehow start updating the game again, or maybe some other team takes inspiration of this game
negative · reviewer's own thumbsView post →I personally did not enjoy much of this at all. The building was VERY clunky and just was not enjoyable.
negative · reviewer's own thumbsView post →bad game after an hr and no recent updates. DO NOT BUY.
negative · reviewer's own thumbsView post →Great physics and sandbox game but aircrafts are all restricted to a realtively low flight speed. Might just be because the maps are kind of small and not super condusive to fast-moving flying vehicles
positive · reviewer's own thumbsView post →Yeah I would say that this is a pretty amazing sandbox game for anyone who likes making things, and I would definitely recommend this game to people who like planes, cars and other vehicles
positive · reviewer's own thumbsView post →Trailmakers is a much better version of this game.
negative · reviewer's own thumbsView post →Great potential, but WAYYYYYYYY too hard to build ANYTHING.
negative · reviewer's own thumbsView post →it is a very good game for people who want to learn about coding and build vehicles at the same time. would recommend.
positive · reviewer's own thumbsView post →I liked the game but I guess they ran out of money. Abandoned! What a shame. Refunded and unwish listed.
negative · reviewer's own thumbsView post →This game is one of a kind. I enjoy making all kinds of flying machines and designing flight controls. There is no other game where I can imagine an idea, make it into a concrete zany whirlibird of some sort, design controllers and nav systems for it, and then have my creations navigate and fly themselves, or have their own automatic dogfights in a real physics-based robot free for all. The combining of programmable control systems, physics modelling, and damage models is really incredible. I…
positive · reviewer's own thumbsView post →Its like scrap mechanic but you NEED to know rocket sience
positive · reviewer's own thumbsView post →very dynamic building system
positive · reviewer's own thumbsView post →Ima start with the good things, it has a fun art style, and some people may like the coding. Now for the bad things, it crashes A LOT, the coding can be tedious, the textures are super low quality even with super high gfx, and finally; this game is not getting ANY more updates.
negative · reviewer's own thumbsView post →most fun ive had playing a sandbox/machine building game definitely recommend to anyone who's looking to get into these kinds of games and wants a smooth introduction to them
positive · reviewer's own thumbsView post →I purchased this game because I was looking for games like Trailmakers... This game has a nice base to be a Trailmaker like game but there's not enough content or updates even... The game is i.m.o not worth it since there is like 1 good normal level. Character customization is mediocre, can't change the color of the player model or shape. Overal not enough content to keep me playing.
negative · reviewer's own thumbsView post →Things I really like about the game consist of driving vehicles since they feel super nice and enjoyable, I wish a lot of car games handled as well as the vehicles in this because it is really really good! I also love the customization and vehicle creation though a lot of the tools aren't obvious unless you go through or look up the tutorials. The multiplayer aspect with a variety of shenanigans to get up to is always enjoyable as well! Although... Aircraft and spacecraft are pretty bad since…
positive · reviewer's own thumbsView post →very cool game you mainly assemble things
positive · reviewer's own thumbsView post →I love this game. I'm an engineering undergraduate and this game scratches the itches that I have to build cool things. The physics engine is quite advanced, with lift, CM, and center of thrust all being relevant to all your creations. There's no magical downforce spoiler or something. You have to make the airfoil yourself. Love it!
positive · reviewer's own thumbsView post →I don’t know what the hell I’m doing.
positive · reviewer's own thumbsView post →The game is dead. There aren't any update and the existing bugs won't be fixed. Not worth it
negative · reviewer's own thumbsView post →its very easy to use and so much fun to play with friends
