Nostalgia can be a powerful ally in making a game. The first game that ever belonged to me specifically was Mega Man 3 for the NES. As such, you can imagine that the series holds a very dear place in my heart. Mighty No. 9 is not Mega Man, but it feels like an evolution of the concepts that the series brought to the table and does a phenomenal job of scratching the itch left by the absence of the series.
