Shame the Grinch leak wasn't real but not surprising. Though they should have switched the character reveals from the last two directs around so they could finish on a higher note, I've seen many echo these thoughts.
Seeing people get angry about the Piranha Plant getting into the game makes me so very sad. These left field WTF characters are what make Smash Bros great, or they always were the inclusions I loved the most.
Mr. Game and Watch, ROB and Duck Hunt Dog are all really fun additions. Not everything has to be some third party guest or yet another RPG sword wielder. My teen self playing Melee back in the day would have LOVED this and the adult me in his 30's now loves it so much more than half the characters most people seem to want.
The more classic actual Nintendo characters they can cram in the better imo. I think the inclusions of Cloud and Snake over the years have sent people abit crazy when it comes to third party wants. I don't know.
I would have loved to see Mach Rider and Geno make the cut personally. Maybe they'll come via the DLC.
