Of course they could have done that before releasing the game, but that would probably cause an even later release date...
And maybe they came up with it after they released the game, which is a really good thing in my opinion, cause it adds to the game.
Also: I don't care for Nintendo to make profit, since they need it. I just want more characters to play as, why the f*** would I care that they did it for the profit?
And it's not even sure they did it because of the profit, like I pointed out before..
Wow really? The next game is just the same thing but a little bit different mechanics and different characters.
That's such a one-sided look. You won't give in, even though it might enhance the fun you get out of your game.
