I have an odd request, but I'd like some sort of self-evolving app for my rarely used mini-PC to run. Something like the Game of Life, but not the Game of Life. I've been trying to write it myself in the Unreal engine, but not with a alot of luck. It seems like ground I'm certain has been well tread by others, but I'm having some issues finding any. A few paid games on Steam seem to come close, but have been abandoned long ago. I need a life-sim, or something else that's self-evolving and interesting to observe. Something that is interesting if you even if you never mess with it. And it needs to run on low-end hardware.
