You're right that the story is about needing to survive, that's exactly what I said (at least it's part of the what Aincrad arc is, anyway). But you're not right about it being about a video game.
But that's the whole ****ing premise of the show
Just because you could change to another setting and still have the same basic plot structure doesn't make it any less of it
Also, I wasn't saying that Kirito's training was a compelling plot point or anything. My point is that while the show calls it "EXP grinding" because the characters happen to be inside a game world, it's still just this show's version of "shonen anime protagonist training time skip", which is a common trope, and hence, just further demonstrates how the show REALLY isn't about video games. Kirito's EXP grinding that the show skips over is no different to how the Naruto series glossed over Naruto's three years of training between the original series and Shippuden (and he's suddenly way stronger after the time skip). It's no different to how Goku and Gohan spend years in the high gravity chamber (from their perspective), but we barely see any of this, and then suddenly, Gohan's an experienced Super Saiyan at the end of it. Nobody complains about it in those shows and accepts that it's par for the course in shonen anime, so why is it an issue here?
Comparing SAO to Shonen like Naruto is just offensive
The difference between time skips in, say, Naruto and SAO is that Naruto does it once and we know he's off to training.
SAO just throws timeskips every 3 episodes as an excuse to overpower Kirito even more and the fact he was "training" is not even known until it becomes relevant.
If SAO was a show ABOUT video game mechanics, it would have went into excruciating detail on how the different stats in the game worked, how you level them up and make the best use of them, etc. But since it's just your run of the mill shonen anime, everything is just used as an excuse to make powerful characters who get into flashy fights. Kirito's high EXP level and special dual wielding skill are literally just this show's version of Naruto having Kurama's Chakra inside him as well as his own, and his signature Rasengan technique that he can do as a result even at a young age.
That's the thing, the show doesn't go in depth because Reki doesn't even know about what he's writing.
Impossible level grinding is not compared to a physical god given a background in-universe.
A skill he himself doesn't even know how he got it and that no other player can obtain is NOT comparable to a technique we see the character learn by being taught how to do it
I would agree with you if you said that SAO could have been a better and more unique show if it DID focus on being about video game mechanics (and did so well), rather than just being a run of the mill shonen anime with "it's a VR game world" being the excuse for the characters being able to have these flashy fights in the first place. But that's not what happened, and ultimately, the show isn't very good because it poorly utilises most of the main cast, and gets to a point where the stories it tries to tell are just flat out uncomfortable. Issues with the mechanics and whether or not people would play a game like SAO, are tertiary at best and mostly be written off with "people like bad video games, subjectivity is a thing", or "SAO is a game that lets you live and walk when you otherwise can't, or make love with your ideal girl or actual girlfriend when you are otherwise an anti-social otaku". Even if SAO and the other VR games were badly designed as traditional video games, there are still plenty of reasons people might play them.
There's a multitude of ways to make SAO better, that's just anither one in the list
It being a bad game does matter because it breaks a viewer's suspension of disbelief, the social aspect doesn't matter when things like Pokemon Go have proven that, eventually, people will give up on it and move on
And even so, not everyone who watches this show is well versed in MMO mechanics. Hell, I'm willing to bet most of it's audience isn't. That is just another reason why the game mechanics are so tertiary to the show.
Most of them are not even specific to MMOs.
Anyone thst has played a game can realise the stupid bull**** that's just bad game design
Man, I should go back to watching that because I hear the second season is even better than the first.
Also, thanks for bringing that up so this doesn't seem to come out of nowhere: Log Horizon is great, it takes the whole "trapped in a MMO" and actually works with it and focuses more on the "how to live inside the game" because it takes the death thing in the total opposite way of SAO, as in, you come back if you're killed, meaning everyone has to learn how to live in it as death is not an option.
And the main characters ARE overpowered but that's justifiable since, well, they're a bunch of nerds who have been playing said MMO for god knows how long and are all capped.
