Get Dragon Age, and if you ask this question on the Final Fantasy board they'll say get that. However I'm getting both (among others), but I'm looking more forward to Dragon Age, JRPG's are a bit meh to me.
@jason : i got the xbox for 50 off my bro's friend. he thought it was broken, but i just sent it in for free. the only game i really bought myself was halo 3 odst and prototype. and i traded in prototype to get odst.
You bought prototype? I'm sorry.... Anyways get this if you want a challenge of a game and creatures that could make a grown man crap himself. FF13 will just be grind, storyline, and if they set up finding the uber weapons like they did FF12 im gonna be pissed. BUT, if they kinda threw in a Lost Odyssey style to it I'd be pleasantly surprised. You know what, just get this its worth its weight in gold.
