I'll just quote myself from over at CAG:
You know, I can't tell what people want out of Smash at this point.
I have seen countless arguments that the franchise itself is shallow, "meant for everyone," simple gameplay. "It's a Mary-o game!" I'd hear, as if that were something....valid to say.
And now I'm hearing tons of laments about "omfg, they r can has make it for teh everyone!!111" As if it were occupying some echelon that the same people said it didn't.
You people need to make up your goddamn minds about the whole thing. It was always meant to be the simple fighting game for everyone. The special movies are one button plus a direction. I remember when I thought Street Fighter 2 had difficult moves, but now I see them as so simple it hurts, that when Smash was originally announced, I thought Nintendo was crazy.
And then I played it, and it kicked ass, and that is all there was to it. And I found that I could utilize a bunch of different techs that gave me an edge over other people. And then I found that there were people who could trump even (what I had thought was) my awesome skill. And I'm willing to bet even those people have an entirely different level of people that would destroy them.
Point being is that the game has always been able to be for everyone, and yet contained enough variation available to those willing to seek it out and perfect those skills.
But again it's always meant to be a game marketed for everyone. I think that's the whole reason that it uses mascots that are (for the most part) highly recognizable.
All these advanced moves everyone found were found. There's no mention of them anywhere in official documentation. Instead, they were discovered and perfected by pioneering gamers who - as DMK once told me - "approach the game much differently than you or I."
Now, maybe Sakurai hates all of that, and wants all of it out. Or maybe he's looking for different techniques to put in. We don't know, and frankly we won't know until the final version goes gold and gets pressed onto some silicon. But I somehow doubt he wants to "nerf the whole game" and piss off those people, because he's said time and time again that the people making this game are some of the biggest Smash players ever. Even Kojima said "the game feels finished" when he tried it out, and that was back in summer or spring.
It's four months away. We have no clue about how the final version of the game will ultimately control. All we know is the impressions from a build of the game that certainly isn't final.
Maybe that's what the additional two months of development are for. Originally, the only people who played it was the dev team (which was reportedly composed of people who have played it thousands upon thousands of hours). But this is the first time we've seen it in the wild and playable by other people.
Sakurai seems like an intelligent developer - Nintendo went the extra mile to get him back on board to make it.
And even if worse comes to worse and the whole thing IS simplified beyond belief, then people ought to be able to 1) find new ways to have advanced techs in it, and 2) adapt to what is there already.
Have some damn patience, people.
