Uh... Megaman in the later series is very quick, but it's not his movement that will be what you're practicing... it's acuracy..
If you can take down MM1, 2, 5, X4, or X8 without taking damage (hardest difficulty) then you'll see what I mean...
Also, 2 I think, while the game itself was only par, had the best soundtrack...
and the Rush-Armors of... 5? 6? one of them... were awesome ^_^
