I agree with you. I said it before and I’ll say it again, the Nash reveal trailer was what raised my hopes for the story of this game, but then I saw the game had no story at all until the general story arrived and that was another disaster of sorts. Too many newcomers that add nothing to the story is the number one issue, I believe. And then we have the likes of Falke (is she a Doll or not? Why is she different from the other Dolls if she is?), Zeku (why is he still around after Guy kicked his ass and overthrew him over a decade ago?), Sagat (he learns of Ryu’s demons in the game he actually overcomes his dark side?? What have you fucking accomplished, “emperor/king”?)…
I actually like the inclusion of Seth, but not like this. If I were handling the story, I would focus on two main things: the fall of Shadaloo and the rise of Secret Society. I would include everyone that has a beef against Bison (T. Hawk, Rose, maybe even Decapre over a shitty newcomer like Falke) and let them deal with him instead of an absurd character like Karin and her tails Ibuki and R. Mika. Then the Secret Society part would have an undead (or unexploded, if you will) Nash becoming a part of SS due to gratitude and actually one of the first believers of Gill’s utopia since it was his technology which revived him and allowed him to do (take revenge on Bison) which otherwise seemed impossible to do. Then I would add characters like Twelve, Necro (both of whom I hate, BTW) to expand on the inner workings of SS.
Apart from these two points, I would have a “free” but still lore-based selection of characters. That would include Gouken (what the hell is his story? We see him once in Ryu’s story and then never again), Abel/Seth (either would be the SIN representative. Since Ed is too much like Abel now storyline-wise, Seth would be a better pick, but he [yes, he] would actually find a way on his own to come back to life, showing the threat that AI/digital organisms present and he would go after Juri as the one who took him down), Gen (wow, such a great character getting wasted in just one panel… That’s disrespecting your own legacy, Capcom), mediator characters like C. Viper, Q, Oro (his backstory would contribute a lot to the events happening around the beginning period of SF3) and some obscure/fan favorite characters like Remy (I believe he is the richest character in terms of lore, but is slept on. Connect him to Nash at this point or something? I don’t know), Fei Long, Rolento, Retsu, Geki etc.
BTW, I was expecting to be proven wrong in the end, but nope, the best storytelling in the SF series still goes like this:
SFA3 > SFIV > SFV
