In my opinion, Mario or Mega Man are the best games ever made. The company that made Mario(Nintendo) revolutionized video gaming, and always does. The same goes for the company that made Mega Man(Capcom...resident evil? street fighter?). Not only that, but, each character has more games than you can shake a stick at.
I know that there are 47 Mega Man games. Mario, I'm not sure about.
I like both characters, but prefer Mega Man.
