Not out yet, but No Man’s Sky is right up your alley. The goal is to explore countless planets, and you can exploit the resources found on them, kill all the wildlife or…just leave everything be. Should be cool, as so far as I can tell, your goal is to explore and discover planets untouched by man.
The game boasts countless galaxies to explore, and apparently it keeps creating planets on its own as time goes on. Not sure how that works…but no one playing is guaranteed the exact same experience.
What I worry about is with so many planets to explore, too many of them will be similar.
The game also plays online, so you can find planets discovered by other players, you can fight other players if you choose, or if they choose…some wildlife can be hostile, and you can kill them. But read about half a paragraph about this game anywhere, and the goal is to explore. Not sure how the colonization works, but I think there’s supposed to be some elements of that in there.
