Well, I just sat down and played with Guile for the first time, and I rocked the house with him. Whats wrong here other than maybe you just suck with him? His Supers are incredible, and his Exceed is very easy to pull off...I got into a fireball contest with Mr. Karate and was outpacing him with Sonic Booms!
Guile has plenty of normals too, the only one that sucks is the Knee because it brings you right up to the opponent and is blocked most of the time, then you can get Supered easily with it, but his Bare Knuckle and Standing Strong Kick is very effective for countering all sorts of shit. The Standing Strong Kick has good range, its like a step-in side kick that is suprising...nah...there's nothing wrong with Guile, and he looks fantastic, I think they did a wonderful job with his sprite.
Overall I'm very pleased with this game and most critisism I've seen comes from a few main things:
a) It's not MoTW
b)It's not original SNK(I.E....its Playmore, some just hate Playmore)
c)Hit Detection...the only solid complaint, but its not a big enough problem to disown the game and Playmore. Seems like most people who hate this game either suck at it and aren't good enough gamers to overcome this minor problem, or haven't even played the game yet and are parroting critiques of members who they think have some sort of 'street cred'.
