Stages aren't on one continuous map anymore? It looks like an MSX game now. And wow at the Easy Mode. You take less damage, get more health back from pickups, and there are platforms over most pits. Not that MMX needed it; the game's pretty easy for a Mega Man game.
Yes, being able to buy all the upgrades is stupid. But if someone's that weaksauce at Mega Man X and they or their parents have the bucks to spare, that's their problem. However, if you are able to start any game with everything you've bought, that might be fun to play around with, like freeplay in Maverick Hunter X. Hadoken-ing the Bee Bladers is fun.
