Fable 2. That game is fantastic, whereas I'm 2 hours in Fallout 3 and forcing myself to keep playing it. I want to like it, but its really boring right now.
I caught on to Oblivion fairly fast, I'm hoping FO3 picks up soon.
GOTY Contestants this year: Dead Space 2, Dark Souls, Tales of Graces f. Everything else can suck it.
