Year: 1989 Platform: NES It might not have had much in the way of innovation, but Mega Man 2 made up for it in sheer, perfectly designed fun. While the first Mega Man experienced poor sales, Mega Man 2 was a commercial success, still the best-selling entry in the entire Mega Man franchise. The graphics were simple yet effective, while the lessened difficulty made it far more approachable than its predecessor. Often referred to as the best in the series by hardcore fans and critics alike, Mega Man 2 is one of the best action-platformers ever released on the NES.
