Here's what I'm playing currently:
PC: Almost done checking out all of the classes in Dungeon Defenders. I have a youtube video if you want to see what the game play looks like. I'm half way through the adventure game Tales From The Dragon Mountain: The Strix, it's kind of a dud, avoid it. I have Skyrim on pre-order, can't wait!
Wii: EA Active 2 I picked this up for $20 it's great so far, I feel half robot with the glowing accessories that monitor my heartbeat and movements. It's giving me a good workout and after I'm done with the 9 week challenge, expect a review!
PSP: Worms Battle Islands
3DS: Currently collecting dust, waiting for Mario 3D to arrive.
DS: When time allows, I'll be firing it up and playing Final Fantasy 2.
