My absolute favorite entry of the Mega Man franchise and easily my favorite NES game of all time. Fun gameplay, awesome level design, groovy boss battles, excellent replay value, and my favorite classic video game score of all time. MM2 made me a fan of the franchise and became the gold standard the rest of the series tried to emulate. I can't tell you how much I love this game and it's the oldest game that is still in my Top Ten favorite games of all time.
