Best Megaman ever created by capcom!
Sound: Awesome and very original. Much memorable as Megaman 1's soundtrack which was just phenomenal. I'd love to here those songs orchestrated any day.
Gameplay: Incredibly fun! If you want a awesome NES shooter or platformer, Megaman 2 is your go to game. If you have it already, you love the controls and gameplay. If you don't....find it and blow in a cartridge.
Graphics: Megaman 2 put everything that an 8-bit console could handle and then some >_>. Perfect 8-bit graphics and will always remain that way. NES's best graphics IMO.
Final Comments: Dr. Wily's castle was fun and all of the memorable levels boss battle were flat out sweet. Megaman 2 is an instant classic and very great. Also this was the first game with bosses larger than life. It was sweet!
