I didn't know that, but I think my point remains. Nintendo didn't create these franchises, and like you said, they did little to promote them. The Eternal Darkness example is a great one. Nintendo could do something with that IP, but I don't think anyone would ever say that it's a Nintendo IP, even if they hold the rights to it. But even if we want to say that these are indeed Nintendo made franchises, what I want to see is stuff made by the in-house teams. Or hell, even Tose, as they're responsible for some of the best Nintendo stuff.
And I think I'd even be happy if they would trot out some of their lesser franchises once in awhile. I loved the new Punch Out!!, and I'd be all over another Wario Ware. It's been years since DIY, and even longer since the last "real" entry in that series.
