This is really where Mega Man started. It has everything going for it too. Firstly, pleasing and charming graphics, in spite of NES limitations. Secondly, the soundtrack is phenomenal, not just back then, but now; best NES soundtrack easily and it isn’t close. The levels are very engaging, hitting a sweet spot of tough but fair. The Metal Blade invalidates a lot of enemies but, man, it’s fun to use. In my review of Super Mario Bros. 3, I mentioned that it was a contender for one of the best NES games and holds up in modern times. Mega Man 2 was the most poignant example in my mind that stopped me from definitively saying “the best”
