I'm playing the zero collection right now, and I am very disappointed.
It's like "Hey, let's take Megaman, add all this superfluous poo poo, add a chocolatety story, no direction on how to do things, and sell it!"

Seriously, spent 30 minutes trying to talk to that scientist before I worked out that you had to stand on the other side of the room before trying to talk to her. Bad, bad design. I would shoot the people who designed Megaman Zero.

If you haven't played it before, I personally would not bother. Go play the classics, at least they don't pretend to be something they aren't.
