You know, I wasn't going to say anything else about sales and how it's not a reliable argument, but I think I will now.
My problem with arguing that sales matter, is that nobody has EVER proposed how the sales are proportionate to one another. Sure, Mario and Pokemon sell a lot. But care to explain how Fire Emblem has almost as many as Mario now? They're not even close to one another saleswise.
It's an inconsistent point. If Sales mattered nearly as much as people are saying it does, Donkey Kong would have more, Star Fox would have less, Wario Ware would have more, we should probably have like 12 more Mario characters because of the vast amount of units that have sold for that series. Hell, if sales were THAT important, Waluigi would have gotten in over Rosalina because of the combined sales of spin off games. Clearly.
You can't say it doesn't work like that if sales matter. It's not a pick and choose. If the argument is that "More sales = More characters" then this has to prove how ridiculous that sounds.
POPULARITY on the other hand is a completely separate beast from sales. There are two sections to popularity. General popularity, and Smash popularity. For example, Wii Fit Trainer wasn't requested by essentially anybody. Yet, Sakurai picked her and made her unique. I would say sales were probably a factor. But I don't think Sakurai looked at her and said, "Wow, Wii Fit sold a lot. LET'S ADD HER BECAUSE OF THAT".
How about Greninja? Sure, Pokemon sells a lot, but why would THAT on it's own get
Greninja specifically in the game? That had nothing to do with Greninja specifically. He was picked because he was unique and new. That wasn't because of sales.
I might have said "sales absolutely do not matter" the other night. But that wasn't an accurate statement. They matter. But they're not nearly as important as they're made out to be. They should not EVER be the deciding factor in a character getting in or not. It should be something to
consider a character and for them to be noticed and considered.
