Holy crap this is fun. Reviews say it's just like the first XML, but as I see it, it's a lot better. Nothing's really different, but they changed all the minor things in XML that made the game less fun. So, things like the fluctuating difficulty, glitches, types of story levels, etc. were improved in my opinion (at least so far where I am in the game).

Party: Magneto, Wolverine, Nightcrawler, and a fourth character that I keep switching. =P
