So, I beat Mega Man X2 yesterday.
Compared to the first game in the series, X2 was a nice continuation, but not without problems. While I find the concept behind the 3 X-Hunters to be cool (They lurk in hidden chambers in the normal stages, which you have to hunt them down and defeat all 3 to get the best ending), I ran into one frustrating bug where, even when I went to a stage where one of them was hiding, the door to the chamber he was in would not open. I did manage to eventually beat it with the best ending, which was enjoyable. In fact, I loved the final form of Sigma for how sinister is was given how simple in appearance it was compared to his final form in the first game (Instead of this gigantic being that takes up the entire background, it's a wireframe of his head; which looks very alien).
All in all, X2 was a nice follow-up, if you get past the few problems
With that out of the way, now I'm onto Mega Man Rockman X3.
