@Shanobi: Yes, it was one of the easiest games on NES and MM2 happens to be the easiest game on the series.
I have to assume that you haven't played either MM2 or MM, since otherwise you'd know how much different the games are. The first Megaman was hard and you could even say controls were "unfinished" (although, intentionally).
With Megaman 2, Inafune basically built the game up from scratch, the controls were better to handle, there were a lot more weapon/health energy power-ups available, environments were made to look more appealing (there were themes to make the levels more colourful), the duty robot idea was ditched to make the robot masters more imaginative and the game turned essentially into a platformer. Megaman 2 actually created the formula that was used in later Megaman games, not the first Megaman.
The thing that made Megaman 2 sell better was because it simply was more fun to play. Megaman 2 was Capcoms Super Mario Bros.
