Today I downloaded the new (old) X-Men Arcade game on XBLA. And sure, it plays exactly the same as I remember it, but I was met with two surprises.
 
1) The music is awesome. It is perfect arcade beat-em-up music. I'm not sure if it has been remastered in any way, but it's great.
2) The voice acting is HORRIBLE. Maybe it was because I always used to play it in a loud arcade and could never actually hear it, or maybe I just didn't know it was bad when I was eight. Here's an example.
