The great gameplay and good replay value cover up for the few visual and audio flaws.
The gameplay is very good, although it may sometimes get a little frustrating, and may seem to simple for some players, mainly because it's all button-mashing and a beat-em-up game. But in my opinion, the gameplay is very good and the fact that your have such a big cast of characters in the game.
The bosses in this game can be a little difficult, and are pretty memorable, especially when you fight big enemies, like at the beginning when your fight this giant dragon Fin Fang Foom. But along with the large bosses, there are normal sized bosses, such as Bullseye, from the Daredevil series.
The sound of this game is normally very good; although the attacking sounds may occasionally be a little behind when you actually punch someone, but they are usually spot on and very good.
Overall, this game is very good, and it's not just for a major Marvel fan who knows all of the characters, because the game has a unique storyline, where you can just jump in to this game whenever you feel like it and start right up.
