Thanks for the replies guys. I see that it is cheaper. But I've been reading some reviews on this and some have said that the gamecube version of the megaman collections played weird. They said that the controls didn't play the same as in the original nintendo. Of course, I'd understand that since they are different controllers, but it shouldn't feel like a different (or as this one particular reviewer intended, a bad) experience.
Anyway, I would also have to get a gamecube controller right? Because my wiimote won't work with gamecube games, right?
