If you are going to bring up a Metroid game, I can assure you, it would have sold just as badly, nevermind a new IP.
The blame for the sales failure is directed at the WiiU itself, not the game.
A new Metroid would have had a lot more hype than another Donkey Kong. It might not have sold as well but it would have made a bigger impact on hardware.
Sigs are dumb. And so are you!
