Games I play that save the world

I've finally started reading Reality is Broken and I learned about some great games that harness the gamer superpowers to make a real difference in the world. The first one is Chore Wars which turns doing the housework into an epic multiplayer adventure. The second is Foldit, where folding proteins is turned into a game. Scientists need to figure out how to fold proteins so they can make medical breakthroughs. Except there are millions of ways they can fold and even supercomputers take forever. If you don't want to play, you can also just lend them your computer's spare time.
