FF13, possible Xeno- games, need I say more?
I give Microsoft props for picking up Halo, Elder Scrolls (Obliv & Morrowind), Jade Empire, Transworld's various sports games (snow/skate/surf), and Prince of Persia.
Also: My PS2 has never once crashed. It's smaller than an Xbox. It has more interesting games than Gamecube. In the future, I don't see how this will change much. My sister's Xbox has frozen about 10 times total, which is kind of annoying. And no, its not one of those first-edition ones that had so many problems. It happens to the systems my friends own as well. As for Nintendo, they haven't put out a game that seriously enticed me to buy their console since n64.
