It's not bad but it's overrated
First off, it says that you can create your own A.I. character. I thought you can customize there looks but you can't. You just basically choose a fighter from the game, name them and train them. The fighting is very fun, about as fun as a Tekken game. There are only 13 playable characters but all of them are great and about equally good.
The graphics are great. The textures look great, the characters look great, the backgrounds look great too. The music is also very good. But the game isn't long at all and with so little extras there isn't much to do after you've beaten it with everyone. Multiplayer is very fun though.
This game is worth the $5.99 I paid. It's overrated but it's a great game overall.
