Hrmm...the 3d models look...bad. This woulda been much cooler as a sprite based (or hi-res models ala the Street Fighter HD games) brawler. Seeing the Powerpuff Girls and Samurai Jack in 3D is just awkward
Wait... this is Super Smash Bros. with Cartoon Network characters? Well, it doesn't look that bad. I recognize most of the characters despite not knowing their names... but what's more important is how good the gameplay and controls are.
Now, if they will make a Super Smash Bros. game with Hanna-Barbera characters... ;D
