So, got the robot masters down, and off to Wily's Castle. The stages are hard if you don't know what to do, but after a couple lives/a game over, they get pretty easy. I think my only complaint with the game so far is how useless a few of the powers are. The bosses are easy with just the Mega Buster, except Concrete Man
As far as the storyline goes, I'm not sure if this has been confirmed or not, but it looks a lot like the tie-in between the original Mega Man series and Mega Man X
