"Outbound is a cozy camper-van exploration and crafting game. There is a focus on sustainability. The game takes place in the near future where humans have managed to defeat climate change and pollution. Everyone lives sustainably. Wind farms can be spotted in the released footage, and there is no coal or oil mining."
While I don't think that every game has to be like this, it is an interesting idea.
