There's seriously, NOTHING wrong with this game
My list:
Pros:
*30 dollars!, We're ripping THEM off!
*This game is just as good, if not better, than KoF and Street fighter (I Love Both), you have to play it to believe me
*Fluid, Responsive controls, can be changed from the D-pad to the Analogue stick
*This game is ridiculously hard. Thank god the CPU level can be changed
*There's multiplayer, ad hoc only, but we all know there's hardly any chance of infrastructure in any fighting game on PSP
*PLENTY of unlockables, such as character colors, mostly Illustrations, but theres more than enough of them
*The fighting is fast paced, just as any fighting game should be
*Plenty of moves to pull off, some are really colorful, more than decent animations
*The story mode is excellent. Plenty of dialogue, although its in Japanese, there's nothing wrong with reading a little English text
*Friendly to pick up and play
*Plenty of characters to chose from, there's a total of 25, all of them are unique
