17 Mega Man 9
Mega Man 9 represents what the series used to be like before fancy additions like Dash Boots and wall-jumping. More difficult than Devil May Cry 3, less forgiving than BattleToads, and almost as maddening as Ghosts 'n Goblins, this return to old-school form for Capcom could go down in history as one of the most difficult games ever made. Leaving the X series and its embarrassing anime-related spinoffs, Mega Man 9 once again pits the Blue Bomber against Dr. Wily and a new crew of Master Robots, showing that simple 80's style gameplay can still be more punishing than life itself in the right hands. Capcom's love letter to the 8-bit era packs impressive challenge, toe-tapping chiptunes, and retro soul in a great Wii game.
