Well, I was just saying, saying that I technically like to download all DLC characters for a video game, regardless of how good they are; though that may change if an exception comes in the future.
Oh I know, I was just taking a (well-deserved) jab at WC3R. That said, even if I don't like the characters and the entire pack sucks, I think Ultimate is so good that it's one of those rare games that deserves more money, so I don't feel too bad about just pre-buying the FPs, Sans, and Cuphead. They're all also just worth it to me. Just my $0.02 and my opinion but it's how I feel. I just wanna support Sakurai even if I don't get Geno, Paper Mario, and my other top picks. Plus he gave me Banjo-Kazooie, so...
The biggest issue with your Pokemon argument is that, with Three Houses, you had 4 to pick between... with Pokemon, you have around 100 to pick between, with the starters being their answer to the "house leaders". People will call the choice a shill pick regardless on who it is if we are getting a Pokemon, which is why I hope for Sylux concidering Metroid is rather under representative and MP4 could need some advertisement
I don't necessarily agree with it being a shill pick if it's a character that people like. Byleth isn't even a shill pick, they're just a selfish pick, and Sakurai's allowed to have a selfish pick after bringing us Banjo-Kazooie, Ridley, King K. Rool, the Belmonts, Sans and Cuphead (sort of) and everything else he's managed to stuff in Ultimate. Again though, had Byleth been replaced with one of the new DLC characters, that would be both selfish and shill.
A Gen 8 rep would be an "obligatory pick". Urshifu would be both obligatory and shill. A favored character from Gen 8 (pick ANY of the ones already in the game) is still obligatory but not shill, yet still does a fine job advertising the game anyway. Honestly, I don't see him picking Urshifu if we are getting a Gen 8 rep, unless heavily pushed by Nintendo/TPC. He himself simply wouldn't pick it though when we have enough fighting-esque characters, two of which are FROM POKEMON ALREADY: Lucario and Incineroar. Tox would bring a lot to the table, especially if you focus on their poison and "sound" typing ("sound" not being an official type, obviously, but focus more on it than doing things like Thunderbolt), along with its punk/rocker vibe.
Or just add kung fu bear and let him chill with Ryu and Ken I guess, whatever. Edit: and Terry. We have enough "fighting" characters, if that makes sense.
