When Steam Greenlight launched a few months ago, it gave PC gamers the chance to pick and choose those titles which looked particularly gorgeous and meaty. Since then, a barrage of titles have been approved for launch on Steam through the initiative, and games that we may not have spotted otherwise are slipping into the limelight.
Still trying to decide what you should this this fall? Maybe you should save some big, big trees. FLY'N is a platform/puzzle game by Ankama Play that's coming to the PC later in 2012. Its gameplay revolves around the resurrection and protection of gigantic World Trees, so you can have fun while saving a virtual environment! Just don't pitch your real-world garbage on the ground as you play. The irony would kill us all.
