Possibly best fighter for GBA,but is still has it's flaws.
Despite this,this is still much better then any fighter on the game boy advance,and is definitely worth a look.
It has good graphics for a gba game,and story mode is devoloped like many other fighters(tekken comes into mind) with a explanation what would have happened if the fighter you played as won.
It makes up for the game boy's lack of button's, with relatively simple control's , and makes it so button-mashing won't help you as much as most fighter's.
The combo's are simple, with not many punch\kick's in a row, and some attack's like the hadoken and such.
The character also has one very powerful attack,like the super-hadoken for ryu.
The flaw's in this game are, it is over relatively soon,and once you have unlocked all the character's there's not much too keep you playing,except for the exceptional multi-player mode ,and bout's of boredom.
Also some character's e.g dhalsim,with his rubber limbs,have an advantage over other character's in this game.
If you have a game-boy and like fighter game's,pick this up as it is cheap and will hold your interest for a while,but don't expect to get absorbed into this title.
