I have both Ultra Bust-A-Move and Tron 2.0
I have played bust-a-move online a bunch of times before halo 2 came out. I have not yet tried Tron online but I played the mutiplayer with a few buddies and thought it was pretty interesting. Mainly purchased for the single player and I'm a fan of Tron.
Send a Friend Request and if I see you online I'll try to play.
