Now that 24 hours have passed we have our winner!
A huge thanks to @frezik@midwest.social for suggesting this awesome idea!
A survival crafting game where the tech tree goes backwards. You start in a prepper hole with working water filtration, food sources, etc, and everything is nice. Then something breaks and maybe you fix it. Something else breaks and maybe you fix that. Three things break at once, and at least one of them is going to stay broken. Have to do something more primitive and time consuming.
Eventually, enough things break that it’s no longer sustainable and you die. Game ranks you based on how long you last.
I would also like to thank every person in the comments for making their wonderful suggestions! I've read through every single one of them and all of them are really good!
You can view the game's code at https://github.com/SamLeeway/project-196, which is currently empty at the time of writing this, but every day from now I will contribute code there.
The game currently does not have any name other than "Project 196", so I will probably host a poll when we have at least something playable.
When the game would be playable? Making games ain't easy so it's pretty hard to estimate. I would say in around a week or so I should have a rough prototype if things go right.
Update
Didn't really have much time to work on this this week, so my week estimate is going out of the window. I will not estimate anymore. But I am still working on things, so game will happen. :)
a traffic engineering game where you have to design different cities as efficiently as possible to allow traffic to flow smoothly to and from various points. different goals can be met for different stages, like: connect zone a to zone b with maximum flow possible, cut pollution in zone c while keeping flow above a certain threshold, make traffic take so long that eventually people will abandon their cars in the middle of the road and start walking to their destination have crashes exist, and cause congestion because of gawkers have a setting for the shittiness of the drivers
build a metro, got it
Focused on public transportation and pedestrian use.
Haven't played it, but I believe Mini Motorways is something like that.
