7. Mega Man 3
OMG Protoman is Megaman's brother! Well, in as much as robots can really be brothers. In which case, wouldn't every robot Dr. Light (or Right, or whatever he's called in this one) created been brothers? Not that any of this matters at all... Here we have another excellent Mega Man game with all of the difficult (but amazing) platforming, shooting, and some of the greatest game music for its time (or ever).
