Thanks! There are a couple flaws, though, now that I think about it. For example, one non-Nintendo game can mess up the percentages for a franchise with nine or less games.
Under the 75/90 Rule, I think Mega Man would qualify. Basically, an historically Nintendo franchise would qualify despite the fact that they support every console equally in recent times. Yeah, you could raise the numbers, but you would have to raise them pretty high considering how many Mega Man titles Capcom has released for the NES, SNES, Game Boy, and Nintendo DS. Maybe an additional requirement that at least one title has been developed, published, or distributed by Nintendo could solve this problem... or maybe it's not a problem at all.
NIWA's decision on a franchise like Mega Man will really say a lot about what direction NIWA is going in. It basically answers whether NIWA will be like the United Nations or the European Union - not everyone will understand the comparison, but those who do will realize the big fork in the road.
