It's kind of a toss up between Dragon's Dogma, Kingdoms of Amalur: Reckoning and Tales of Graces f. Kingdoms of Amalur, I played for a straight 2 and a half weeks after I got it before touching anything else. Tales of Graces f(while not my favorite Tales game) lives up to the franchise within which it exists and is a fantastic game, very fun to play. As for Dragon's Dogma...I've been playing it since I got it on release day. Still playing it. If I go to play something else, I go back to Dragon's Dogma within the hour.
