THE SHORT: Neat photorealistic graphics of very awkward looking characters coupled with a White Zombie soundtrack....equals wasted potential.
THE LONG: 6.5!!? At the time of this writing, 4 people have voted to give this game an average of 6.5. No people, it is not that good. It's not above average, or even average. The game basically sucks.
Take a handful of colorful yet mostly generic, awkward looking characters (one of them resembles a shirtless, skinny Hitler) and give them bad animation and a bunch of moves that are difficult or impossible to pull off. Then throw in White Zombie music to pump your adrenaline more, and after a while of this you will turn into a hulking, enraged beast without ethics or mental control determined to attack the game itself and anyone you know who is aware that it exists.
Seriously. The moves work sometimes, sometimes not. Even jumping or turning around can sometimes be a chore. Again, a few of the characters are unique (ooh, ooh, lemme be the trailer trash biker chick!!), but regardless who you choose, you won't keep at the game very long. Unless you're desperate, or part of some perverted scientific experiment.
I guess I've played worse. The original Gameboy Mortal Kombat sucked, as did Mortal Kombat Advance for the GBA (I'm no fan of Super Turbo Mega Vs. Special Olympics Street Fighter either, but at least the game doesn't just flat out suck). But really, for a system as capable as 3do was, this really, really could have been a better game.
