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. :)
I'm thinking an interface like papers please with some more expression and color.
You start as a hermit. Farmers and peasants come to you with problems and you craft spells, hexes and curses to cast on them. Sometimes you give them what they want, sometimes what they need and sometimes you throw a fireball. Maybe some rapid responses are required.
You gain a reputation and move from your shack into a town, and then into a castle where you become a court magician. Higher stakes, more options, more magic!
Get creative with how elements combine and have long lasting or delayed effects!
Not quite the same but you should most definitely check out the Wizardry! series
