Alright I'm seeing a lot of points thrown around again that kinda bug me so I want to give my two cents on
,
and improving on third-party content in general.
I think people are looking way too hard at the whole "representation" angle and assuming that Sephiroth was added with the explicit intent of improving and / or "fixing" FF7's content. As I've said in the past, while I'm sure this could have played
some factor in the decision I think it's ultimately another arbitrary excuse that limits our perspective. Fixing FF7 did not need to go as far as adding an entirely new character. Sephiroth justifies himself.
My major takeaway from Sephiroth was not that he was added to expand on FF7, but that he was added
in spite of FF7's existing content because Sephiroth is an incredibly significant and popular character who needs no introduction. Same could apply to Tails, Eggman, Chun-Li, etc. It's not like the potential isn't there to expand on these series - Sonic and SF have serviceable content (admittedly yes, much better off than FF7 was but... who wasn't), but plenty of history that has gone untapped and countless characters, music and locations that have yet to be explored. I think the mindset should be less "does it necessarily need more content" and more "is the opportunity there?"
In Sonic's camp... well, he's actually got a surprisingly great spirit lineup, but Min Min and Pyra already show us that we don't need to add
that many new spirits. Music-wise Sonic will pretty much never be complete, and then his two stages pretty much cover the same general idea while Sonic offers a huge variety of locations to pull from. Eggman and Tails could offer fresh new movesets and mechanics and are insanely popular characters in their own right.
If Nintendo wanted to add one of those two, they would not struggle to find content to fill out a new challenger pack whatsoever.
I feel like it's worth mentioning that Final Fantasy actually has better sales figures than Sonic overall - not by much, but I feel like it's something that doesn't get acknowledged enough. Sales aren't everything, but the flipside to this is how we already know Sonic performs better overseas than it does in Japan. This also leaves the only third party on the roster that performs better than FF as... Minecraft. When you take all this into account it actually makes a good deal of sense why FF would take some precedent in getting an additional character in the first place. This isn't to disqualify the opportunity for Sonic either, but when people act confused as to why Sonic was skipped over or whatever... I'm surprised nobody ever suggests this might be part of the reason why Sonic has to wait his turn.
So why else Sephiroth? Well he's one of the most famous villains in gaming, FF7 is super relevant and has a slew of new related content on its way, Final Fantasy is one of the most successful series represented in Smash... I want to suggest though that Sephiroth was
also the most significant SE character after Cloud and Hero themselves. Taking representation of new series out of the picture, putting every single character on an equal playing field where representation is not a factor... it's Cloud, then Hero / Erdrick, then Sephiroth. No question. So is it really that odd to imagine that Nintendo would see the potential here independent from "representation" or from Square pestering them themselves? There's so much more to it than fixing FF7, but that was certainly a really nice benefit to Sephiroth's inclusion.
