Guy's real easy to learn 'cause he's so goddamned fast. I leaned more towards Jade though because even though he's slower, his combat artes were really easy to use... and you could just run back and cast something epic like Thunder Blade from the background with 9 times out of 10 the enemies aiming towards characters like Guy or Luke.
And then there's Mystic Cage and Indignation... :33333
I found it quite fun. I played ToS afterward, and although I liked it, it seemed a lot more "kid-like"; the ending was screaming "And I would have gotten away with it too, if it weren't for you meddling kids!"
Either way... THUNDAR LANZZZ x500 (Actually when I finished the game for the first time I used that move over 1000 times XD)
