I've gotta admit - Oblivion for the 360 appeals to me.  A lot.

It seems to specifically embody the concept of "role-playing" - i.e., enterting a world that's about doing what you want, how you want it, and being who you want to be in the process. 

The review shocked me with how glowing it was, how much better the game is - apparently - than it's predecessor.

Perhaps I'll find time and money to swing both a 360 and a PS3 in addition to an HDTV this year.
