Everyone knows what a Mega Man is. Only turbonerds what a Proto Man and Rush is. Mega Man 2 exists on a level of quality and popularity that the most of the franchise could never hope to resemble.
Mega Man 2 is the 21st best selling Capcom game of all time, circa 2010. The next best selling Mega Man game is in the 40s, and it's X1, not any of the NES games. You'll notice that they sometimes reference things from Mega Man 3, sometimes, but almost never anything from 4 through 6. This is because 3 is the 3rd best selling Mega Man game.
Every Mega Man game ever made other than 2, 3, and X? Didn't even sell a million copies world wide. They killed this series for a reason. Almost every Street Fighter, Resident Evil, Dino Crisis, Monster Hunter, and Onimusha game has outsold any of the Mega Man games, including 2.
