Tourneys are pretty much your only valid complaint.
Yes, they're kind of a mess right now, but I think one might be willing to give them some time, as frustrating as it may be, to fix it. If it goes unfixed forever in the face of fan feedback then it is a problem.
Otherwise, get the fuck of your high horse. The man has crafted an experience that is unlike anything else in gaming. He's a genius, even if some (read: very few) of his decisions are frustrating. He's an amazing individual who we should consider ourselves lucky to have working on this series.
Sakurai is Smash. I'm distrustful of the ability of anyone else to consistently deliver an amazing Smash experience.
Been reading this back-and-forth argument for awhile, and I just wanted to pop in and say that you nailed it. I completely agree with you. Anyone saying that Sakurai has peaked or doesn't know how to make fun games anymore or has a flawed definition of fun might be right where their own feelings are concerned, but they are completely, objectively wrong otherwise, because many of us find Smash 4 to be the best game in the series yet and have had more fun with this game than we ever did Brawl, Melee, and 64, and that's saying a whole lot.
It's fine to have the subjective opinion that Smash 4 is shit or that Sakurai sucks at his job or has no idea what he's doing anymore, but those opinions are arrogantly being thrown around like they're facts when they really couldn't be further from that.
The vast number of people around the world having a wonderful time playing Smash 4 - no matter
how they play the game - fully and utterly invalidate any claim that Sakurai doesn't know how to make a fun game or sucks at his job. Those people invalidate these claims
simply by existing. People are having a lot of fun with Sakurai's newest game, therefore it is a fact that he still knows how to make fun games and does not, in fact, suck at his job - which is to make fun games that people enjoy. Pure, linear logic.
It's arguments like these that make me want to avoid SmashGAF sometimes. Whether you, or I, or anyone thinks Smash 4 is the best game in the series, the worst, or somewhere in-between, I just wish we could respect each other's (educated) feelings on the matter and stop confusing the definitions of "fact" and "opinion." And while some of us have shown that we can do this, others clearly cannot. :/
At any rate, Sakurai obviously isn't infallible, but I'm in total agreement with you in that we're incredibly lucky to have him at the helm of this series (even if a lot of us don't realize how lucky we are) and that there's no one else in the world who could accomplish what Sakurai has with this series. Not even close. He obviously won't be around to work on new Smash games forever, but I can't imagine who they're going to get to continue his legacy because he is honestly irreplaceable in terms of his attention to detail, his rock-solid understanding of Smash's most important and essential qualities (a mix of fun and competitive depth/balance over pure competitive focus), and his sheer passion for the characters he's working with and the games they come from.
Smash 4 may well be the last game in the series that Sakurai develops and directs himself, and if that turns out to be the case, Smash's future will be looking very uncertain and possibly even grim in several years. For now, I'm just thankful that Smash 4 is as fantastic as (I think) it is - and a large part of that (the largest, really) is due to Sakurai.
