This game is fun, but the removed voiceovers and the unreal cutscenes just start killing it.
The graphics are perfect for a 2D sidescrolling game. The foreground moves smoothly while the background moves with it in the right pace making it a great mixture that makes the graphics even better.
The music/effects are really cool, especially this one stage you'll probably love the music and the effects when Zero slashes and when X shoots a fully charged blast. I just love those awesome effects.
Overall this game is great, it is an awesome sidescrolling game with an awesome storyline. But the characters are a bit less interesting in my opinion than the ones in the previous MMX games.
