Yeah, those game are great. Stranded, will look that. There is also Eco. And i would add getting over it :)

Another economical system ? Let's say universal income, bank of time ? Libre currency ? An anarchy system with several democraty system and quadratic vote ? A shared decision along other mayors (players) ? I'm willing to explore those ideas where the idea of grow is simply erased along infinite ressource. Basnished is somewhat close to it as resources are limited.

Something that follow GIEC's recommendation where building the biggest city will result a game over and economic collapse.

Horizontality skill system. Veloren try to do that but it's not what i'm seeking. Maybe soul game are closer as you learn how to be better instead of using skill, weapon, armor ? It would erase the experience point in rpg system. There is no grow. You are just a human with the same set as everyone. No better armor, no new skills. So you can be killed by a new player.

Collaborative game instead competitive one . There are lot ideas to explore as relationship. :)
