Because that direct killed off every bit of hype I had for this game, and I likely won't buy it unless something big happens to change my mind.
I was already steadily losing hype, as Kenith ever so mocks me over, I can't give two flying ****s for any of the newcomers so far. Now that's not to say that I just want every character that only I ask for, but to not be excited one bit while I keep seeing worse characters is really off-putting. Sure Mega Man and Little Mac (and Villager) were great big fan requests, but I don't care about either of them, and the rest of the characters are practically shoehorned in. I guess I can be happy for the grand total of three or so blokes who wanted Miss Fit, Rosalina, and Greninja, but I'm getting exasperated by the growing amount of second rate characters.
That's not what really killed it for me though, now cuts are a thing, and he started it off by cutting the damned main protagonist of Pokemon, with Greninja sealing either Jigglypuff or Mewtwo's fate. Zelda/Sheik are separated, which completely ruins their concept, Zamus is separate too, which just adds insult to injury for Ridley. Olimar was nerfed to hell and back, which really hit me since he's one of my favorite mains, and now he'll never play the same. The game is just ruined for me.
