So, the game is..okay at best. The move system is easy to use, but it gets very repetitive, very quickly. It's not like Street Fighter, where a combination of buttons will execute a move (although you can select that, which probably would be the harder, but more fun way). Also, certain attacks from certain characters are kinda broken. Like Boss (not the Lonely Island song), who has an extremely large range, dishes out lots of damage, and attacks very fast. He's also ugly as hell. It's got a good line up of characters, and I'm glad to see some of the other magazines putting something out (other than Shounen Jump).
