Marvel Super Heroes in War of the Gems is a fun nostalgia trip for fans of classic beat-em-ups and the early days of superhero games. You get to bash bad guys with your favorite heroes like Captain America and Iron Man, and the multiple paths through the stages add some replay value. However, the repetitive level design and somewhat clunky controls can bring down the experience. If you're looking for a deep and challenging game, this isn't it, but for a side of button-mashing fun with a Marvel twist, it's a decent choice.
