How about playing an indie game that's not 3D? Like Cave Story, Darwinia, Flow, Dwarf Fortress, Gish, Varicella, The Shivah, Toribash, Knytt, Frozen Synapse, Warning Forever, Facade, Peacemaker, N, Sam and Max, Kingdom of Loathing, Battle of Wesnoth, Fallen London, De Blob, Dungeon Crawl, Death Worm, The Chzo Mythos (Yahtzee's games), Robot Dinosaurs That Shoot Beams When They Roar, Robot Unicorn Attack...
And The Graveyard is actually a very good piece of programming. Whether it could be called a game is difficult, but it's certainly a powerful interactive experience.
