Classic game=classic gameplay.
For starters, the game had some cheap A.I. and was almost impossible to beat unless you were cheap as well making the game virtually boring. There were no REAL combos to perform although, there were ones to pull off you just had to make your own up. The sound really hasn't changed all that much and still has that gritty map announcer guy telling where you were heading to next. The visuals, although in Hi-Definition, didn't blow my mind like I had hope it would. Online play was a joke mainly because of the lag issues and hardly anyone was playing it so you pretty much had to wait for a while till an opponent was available.
Aside from the flaws and downfalls of the game it was nice to play a game that I had enjoyed at an earlier age and remember what it was like to play a game for the Score. The only way to still play this title is with friends right there in your living room.
If you're looking to play a fighting game on Live Arcade and have never played this to really appreciate it then stay away. You'll only end up dissapointed.
