I do a bit of game hopping myself.
Right now i've been playing Assassin's Creed Brotherhood. (I'm hooked on assassin's creed lately.)

Though at the same time I need to finish Mass Effect II(THough I may just pick up the original first) As well as Borderlands, And I still need to finish Dawn of War II, And Fallout New Vegas, Dead Money. That and the original Assassin's Creed. Though it can't seem to hold my attention.
