But it is relevant in Gate. The world on the other side is very much a place you might find in any JRPG and the main character isn't the only one who sees this. One of the other characters is actually very excited when he finds out cat girls actually exist. And when it comes to fantasies like that, they often end up playing out like the characters imagined them.
Not to mention (again), those fantasy girls orbiting around the main character like a bunch of trope-y moons...
See, that guy, the cat girl fan, jeep driver guy, he is more of what you'd find as a tropey otaku character. And I never said there's no such elements, just that they're not really what the story is about. They're a seasoning rather than a main ingredient, they don't really affect much or go anywhere. You know that guy from Gintama who has a mayo fetish? Otaku traits are the mayo in Gate.
You're kinda failing at anime here...
Look, more often than not, the main character of an otaku show is an ordinary otaku who turns out to be extra-ordinary (or at the very least a chick magnet). He doesn't look special and doesn't care about being special, hence his often humble attitude, but he turns out to be awesome at what he does anyway. While in some cases that is thanks to his otakuness, it's usually a secondary (actual!) skillset or a special power that makes the difference. In a way, it's just an evolution of the common harem manga protagonist.
Gate's main character fits that description perfectly. And just to be clear: he was not an ordinary soldier. He's in the special forces, something he didn't even specifically aim for. He got there by just sort of consistantly doing the minimum.
Subaru subverts the trope, because he expects to be that kind of protagonist. But, he can't act like it and his special power is only useful when he DIES. Aside from the reboot button he's on his own and we see him screw up again and again.
I'm drawing a distinction here. These chars you describe, their primary trait is "is otaku", and then they also have this or that other talent or skill or amazing component.
That's not Youji from Gate. His primary trait is "is kindhearted, lazy soldier". His actions and behaviors are evidence of this. If not, he wouldn't have volunteered to go to the other side of the gate when he didn't need to. He felt a sense of duty and his nature was to go, it had nothing to do with his being an otaku and it even caused his divorce. I don't think that you can say his being a kindhearted soldier is only secondary to the character. That being so, even if the show explains that he's an otaku, it can't help but be again, a small aspect of the character. Seasoning rather than main ingredient.
His attitude of trying to be an underachiever such that he can get the most out of his hobby is also a much more realistic and accurate depiction of an "actual" otaku, so the lack of overly tropey elements that not many people would identify with (or any, even, in some cases) helps make an actual character out of the protagonist.
Ultimately, I know very well the archetype you describe, and I know the type of fun to be had by experiencing such a story. Because I know that, I can be confident in that this isn't that. The entertainment in Gate doesn't stem from the badass actions of the protagonist which lets you have a power fantasy or this or that. It's more about the premise and the world. It might try to have it's cake and eat it too by introducing all these elements, but at worst I'd call it just pandering to otaku on the side as lip service while also telling a really gripping story, as opposed to a full-fledged parade in their favor in the vein of Oreimo or The world God only knows.
The elements you point out are all there but they are so subdued that most of the time, I didn't even feel their effect in the story at all.
If you want to discuss trope-y anime, it really helps to know your tropes [http://tvtropes.org/pmwiki/pmwiki.php/Main/ReallySevenHundredYearsOld]. Also, how does mage girl being only 15 make anything any better?!
I don't visit that site, I don't like the memefications of a lot of these things and people who throw around terms from that site often seem to not understand them (not saying you don't, just past experiences have shown me that XD). But yeah, the elf girl looks grown up and it's common for elves to be that old even in western stuff, the 967 year old girl is clearly a self-aware character since her name is Rori (and she was amazing btw, probably the best char in the show) and the mage girl is 15 which I don't get what's not fine about. It's not like she has sex with the protagonist, she seems to just have a crush and even if she did I come from a country where 15 is the age of consent so that's not at all weird for me, but that's a whole other can of worms I guess lol.
Now, if you wanna call the police over someone, it'd have to be that noble girl who fell for the diplomat, she is worth being outraged over. Maybe you feel Gate is like SAO because her and Silica share a voice actress, ever think of that!? XD
