I would create a sim-city-like environment with real science and history - havent seen that done. eg how to make the first knife ;-) most inventions are accidents; the inventiveness of humans is to then think, "oh, that's interesting, how did it do that? can I repeat it without making a mess?"
Great idea.
I wanted to make a game where you roll a starting character, a random historical time, a random historical geographic location, a random social status, a random set of physical characteristics with a realistic chance of birth defects.
You can only roll ONE CHARACTER.
as ur into games, I wondered if ud come across anything like that? I thought of that 20 years ago! would also be interesting to program it...
ok, how do you make a knife? well, we need a sharp edge... so the first knives were made of stone, but not any stone... then u discover some stones melt and then harden... some can make pots and spoons, some are crap for knives, but some are good... u still dont have the concept of a metal, just that some stones change properties when heated... a primitive alchemy is born... anyway lol
then some psycho thinks a knife is a better way of killing someone rather than as a craft or tool. and so the world churns.
It sounds like it might make an interesting "puzzle game", sort of like,
There are also some youtube channels dedicated to making things like knives using only primitive resources,
