This game is barely in developement yet, but the concept of it struck me, it is so perfect of a metaphor for the Earth, enviroment, humanity, and all that.
It is a sim-city-like game (ok, will be), with the usual stuff (explore, research, advance), but the gimmick is, your city is on the back of a giant animal, so you can't just build whatever you want, you must co-exist with your "planet".
Which moves, so you don't have to release disasters manualy, heh, it wonders into them.
It comes primaly on PC, and though it focuses on Steam in its campaign, it doesn't seem Steam-exclusive, so if you find the idea as good as me, check out Kickstarter.
Here is the trailer:
