Ive gone for a 9 as well!
Its rejuvenated my gaming and it plays like classic SF2 but with enough additional features to make it different in its own right!
25 characters to choose from, arcade mode, challenges and online all add to its lastability! Ill agree with dave and say that the new characters aint much cop compared to the rest. Oh and dave Rose isnt a new character, shes been in some of the earlier SF games!
My only negatives are:
Dont think much of the 4 new characters
Too many kens online
Needs a lobby and tournament option online to make it more fun!
The main drawing point for any SF game is the fact that every fighter only has about 3-5 special moves and they are generally the same movements, IE charge back/forward or half circle etc etc.
So the game is noob friendly but has lots of depth with the various combos you can perform and its all mind games online!
