Megaman got the formula right with Zero, yet it's the shortest of the series thanks to a Tomino style ending to MMZ4... :/
Anywho, DoS? Higher than AoS, PoR, and OoE? What the hell? DoS was a horribly executed, pointless, and rather bland sequel of a game that, even on the GBA, had the better graphics. That's pretty damn sad, IMO.
