Mega Man is the quintessential 8-bit classic, which begs the question - Why not play this game? The hero is a cool little dude with super powers, and he's a robot, what more do you need. Really, this game has great music with that, now classic, Mega Man high frequency vibrato. Also, a formula that works - levels styled to match the boss, a mystery boss, great power-ups, anime styled graphics and a balanced color palette. The gameplay is not difficult, so anyone can play.
