"Its KONY the phony"
I just thing a semirealistic caveman videogame where you kill people with rocks would rock. People could form tribes and thered be crafting and dinosaurs. You could have a couple different tech trees and combat skills.
Like maybe your tech tree is transportation. So youre in charge of inventing the wheel, which will help with resouces and the most advanced shit you could build is like a glider made of pterodactyl wings, idk. Then your combat tree could be grappling and they could build a nice way to do those. I think a prehistoric videogame is very much in order. Open-world, but definately not an MMO. fuck MMOs.
