From a gameplay standpoint I was actually somewhat dissapointed with all inclusions. Okay, I will give Miis that they have 3 movesets, but a lot of their moves are drawn from other characters, but moveset-wise they're okay. But Palutena looks a lot more boring than I imagined her to be, it doesn't seem like she has any unique gimmick other than beams, and Pac-Man's moveset can only be described as a big mess imo.
The movesets for newcomers all seemed so focused and incredibly distinguished up 'till now, even if the playstyles didn't look to be for me, so I'm not sure why these three seem so unpolished to me. I'm not especially excited for any of them, I still don't like Mii or Pac-Man, and it's practically impossible for me to get excited for Palutena when we've known about her inclusion for half a year. These newcomers simply aren't cattered to me, I do see how other people can find excitement in them, but personally I just can't, and it's sadly been this way with all newcomers except Mega Man and Greninja for me.
