Let me guess, he was using storm, Sent, and magneto, right?
High level play in MVC2 is no joke! Thats the game I started on, and it can get nasty.
Things like the Magneto ROM infinite can make total newbies to the game want to scream.
If you want to see some high level play in action, it's a rather big download, but it has some MVC2 stuff on it. If it's going lighting fast and is 2-D, it's MVC2.... (it's a zipped dvd trailer from EVOlution 04, the fighting game championships)

Your in trouble!
EDIT: By "started on" I mean the one I really got into. I've been play SF2 since I was a wee baby!
