If 30 is the limit, then I am disappointed with the decisions for Mario Kart 8.
I mean, I get that you can essentially just have the "Original 8" of the Kart series plus Wario, the two sports regulars (Daisy and Waluigi), and Rosalina as of now and it shouldn't matter who else shows up, but it's rather sad who's excluded (Bowser Jr., Diddy Kong, King Boo, etc.) while all the babies get higher priority with a brand new one and the Koopalings (as great as they are) preventing others from joining in. Oh, and Pink Gold Peach; Metal Mario was acceptable, PGP is just random.
