Games live and die by their gameplay. Great games have varied gameplay, with different ways to solve problems and encounters which require you to change the way you play in order to progress. Dark souls bosses are a great example of this. A defense heavy shield based approach might be viable for some bosses, but not others. The game challenges you to change up the way you play by throwing new challenges at you. X-men the official example is not a great game, its not even a good one. Interesting though, it seems like the developers realised they were making a shitty game and decided to add some variety by sticking 3 games on the same disk, at least that's what it feels like. The game is split into 3 types of level: Wolverine levels, Blue guy levels and Ice Bloke levels. This actually sounds kind of appealing, adding some variety and mixing things up. But now, instead 1 boring and repetitive level type, you have 3. Seriously its all the same. Wolverine levels are hack and slash, smash x and kill everything. Blue guy levels are a bit of platforming then some scrapping, press R to jump and then x to kill everything. Ice Man levels are horrible flying levels that are akin to superman 64. It's a nice try Activision, but if you squish 3 turds together its still poop.
