Good games for Xbox 360?

I'm looking for some new games for 360 to check out, but I'm sick of shooters really. I want a game that I will be playing for hours unlike a 6 hour campaign mode on a shooter. I love RPG's, but there are very few on the consol, I also like games that have a high replay value. I'm probably going to get FFXI. But any recommended games for 360?

Here's a few games I already know you will mention, and I'll tell you I've already played/beat/got bored of them. Fallout 3, Oblivion, GTA IV, Fable 2

Yeah, I was thinking about catchin' that Tales of Vesperia. Have you played it?

Alright. How long do you think the game is?

Alright, good. I like my RPG's long.

Yeah, a freind of mine is going to give me his. I'm probably going to be playing on the Asura server, I don't remember what you told me your server was though.
