A great little comic book-based beat-em up that was sadly overlooked by many gamers.
It had some great looking 2D graphics, very impressive for SNES. The gameplay was top-notch as it mixed beat-em gameplay with fighting game styled move-sets. You could play as Wolverine, Spider-Man, Captain America, The Incredible Hulk, and Iron Man. Your goal was to gather the Infinity Gems and to battle various Super-Villains in various Marvel Universe locations. A thrill for comic fans and beat-em up game fans.
However it had a couple bad-points for it:
1. The cover art was boring. Come on, it was based off of a comic, you could have slapped all kinds of awesome stuff from the Marvel vault on that plain grey cartridge, instead we simply get a label that reads "Marvel Super-Heroes: War of the Gems." That's it, no artwork on the sticker for you.
2. It's HARD! It took me a while of trial and error before I finally beat this borderline torturous game. They don't give you break in the beginning areas.
3. The Hulk looks freaking ridiculous. I mean seriously, what is he doing when you just stand there? It looks like he's trying to make himself vomit.
