If my current avatar/signature set is any indication, I've recently been (very slowly) playing through Bastion. It's a fun game, set in a fascinating world, with a cool story-telling method and a great visual style. Also, I really like the music. I've been considering picking up the OST for a while; I might give in once I'm done with the game...
Besides that, I've also been playing some Pokemon (HeartGold and Sapphire, to be specific) on the side because of challenges.
