I can understand games like Wonderful 101, being potentially a Nintendo IP, but games like Mad World, Anarchy Reigns, and especially Beyonetta 2 would sell on the PC. I heard Beyonetta 2 sold relatively poorly, only because it was exclusive to the Wii U. If they could port that to PC they could still maybe twice as many units. Just trim out the Nintendo skins and it should be good to go.
Yes I know Nintendo helped to make Beyonetta 2 a reality in the first place, but it's not going to do the company any good at this point. Since the Switch made the Wii U completely irrelevant, they won't get any additional sales off it.
