MP Federation Force is coming next year this year, and it looks like it's going to get backlash, no matter how much Nintendo changes the looks or mechanics of the thing. It's very possible that the next time they show us the title, it would be much more different that in E3 2015. I don't know how successful it's going to be, even if it's attached to the Metroid franchise.
What if the game was Free to Play? Instead of trying to sell it for 25-40€ (or whatever price they decide), they try to get everyone to play it with a FTP model, maybe on both 3DS and WiiU (it can't be difficult to port a slightly bigger version for the U). Would that make the game more likable for the public?
They could have called it Space Football Force and it would have been ignored, but not hated. But what's done it's done. :P
