So essentially most of the people that say first party characters are boring are people whose most wanted characters are third party characters
I don't think that categorizing people like that is a good way to put it. Not everything is black and white-
It's I think the biggest issue with the Smash community in general, people saying "wow what a shocker, people who want more first parties think first parties are important" or the recerse with third parties.
My most wanted right now are third and first parties. I'd kill for Sora, Dante, Phoenix Wright, Isaac or Andy.
I would have killed for Chrom pre-release.
I would be extremely happy if peoples get their most wanted no matter what.
I'm just saying that it's really being delusional for people to think that a first party would make a bigger noise than a third party if your name is not Waluigi right now.
First parties are cool.
But let's be honest, beside sadly dormant series like Mother, Golden Sun and others, any first parties are scrapping the barrel of Nintendo characters... And for a "broader audience" I don't think a first party focused pass would hit the same as a third party focused one like the first pass.
Nintendo "raised" our expectation, and it's our fault to believe they would follow that trend.
But it would also be their to lack transparency, even more with Sakurai's comment about bringing more worlds togethers or making fans happy. So far Byleth got actually a good lukewarm welcome because he ended up looking more than a boring swordman and Threehouses is an amazing Game.
ARMS is getting a good reception because it's a new franchise. But if we start getting first parties from existing franchise. This is where I expect fans and the speculation in general to get very much toxic.
