Okay, so I've seen the presentation, so here are my thoughts:
1. Well, Kazuya definitely set himself apart from the other traditional fighting game characters on the roster, though am I the only one who feels like they're going to need some sort of cheat-sheet just to keep track of all his different moves and how they work? Also, I really liked that Golden Suit alternate for him. Also also, that was pretty cool that they got the announcer from Tekken to do his victory screens (which don't have a jingle to them, either).
2. Mishima Dojo looks...alright. It kind of feels like a mix between King of Fighters Stadium and Shadow Moses Island, so we'll see how this goes.
3. Damn, that's a lot of music! And 8 new remixes, to boot! Alright then.
4. Well, time to address the elephant in the room: I gotta admit, a part of me was pretty disappointed that Shantae got the Mii Costume treatment; I'll ALWAYS prefer the character actually be playable over a Mii Costume (where the vast majority just look like Miis cosplaying as those particular characters), but oh well, there's not much that can be done now. At least we're getting a music track with it, and while I would've preferred "Dancing Through the Danger" myself, "Burning Town" is still a slapper from Half-Genie Hero. Also, am I the only one who misses the days of Smash 4 when Nintendo would provide download codes for the Miis featured in Costume reveals?
5. So, all this is releasing tomorrow; I honestly thought it'd be today. Oh well, I was close!
6. Finally, it looks like Challenger Pack 11 will indeed be the final fighter for Smash Ultimate. Here's hoping they end things on a high note (I'm keeping my fingers crossed for Sora).
