Wii is extremely popular and will have some popular rpg's. But besides The Legend Of Zelda: Twilight Princes, I am not sure if I will like their other rpg's...

Super Paper Mario
Dragon Quest Swords
Final Fantasy Crystal Chronicles: The Crystal Bearers
(Aliens game, not sure of the title)

Maybe I could rent it and beat Zelda, but it would take a lot of money to rent it for a month or two. Anyways, Lost Odyssey is helping me make a decision for Xbox 360, combo that with Blue Dragon, which I will be buying the day it comes out. I have to support Hironobu Sakaguchi and Nobuo Uematsu. Playstation 3 I don't need to get until Final Fantasy XIII and Final Fantasy Versus XIII comes out in Sep-Nov of 2008, although I may have it when White Knight Story comes out in Spring 2008. Anyways, I'm still busy with Final Fantasy XII and started playing Rogue Galaxy, they are both ultimate !
