All I have to say here is that your game Solidus is no longer a fighting game but a multiplayer action game that will be flashy, over the top, stupid and not fit for tournament play. Especially if it's split screen. SUCH AS UNS, Dissidia, Tenkaichi etc... Those games can be considered fighting for the genre but the reason they're so looked down upon is because they offer NO depth of any kind into the world of fighters.
This is where I laugh, TvC technical? TvC takes less skill to learn than any (serious) 3D fighter i've ever played, including DoA. Like any game there will be great people playing it and a difference in skill as a person but almost any fighting gamer that's attempted to play seriously can pick TvC up and be a threat, mostly because of the simplified controls and easy full life combos with half the cast. Now i'm not saying it's a one shot deal to do, it's just much easier than most games out there.
Like any game, spacing, timing, reflexes are all needed to do well, 3D fighters have all of this as well as 2D, 3D fighters offers more diverse way around moves and strategies than 2D fighters do just because of the 3 dimensional plain. And that's wrong, at no point do the games need to be able to freely run around in 360 degrees as freely as changing direction on the controller/stick. That would automatically deplete it's ability as a fighter.
2D fighters have gotten flashier over the years but it's core is the same, BB didn't change that much from GG in fact it's also easier in the technical aspects. the SF games haven't changed at all over the years other than basic gimmicks that change how you space and defend. Same with KoF blah blah blah. They're all stuck in their style, in their genre because the core aspect of it is the best aspect we've found in true competetive fighting games. Same with 3D.
