Like the title says, what do you consider to be the common staples of Isekai? What is so generic you see it so often? Do you hate the generic stuff altogether or are there some exceptions? What tropes do you see done right generally and which poorly?
You woke up, in another world, reincarnated/teleported/time traveled/quantum tunneled/got trucked, and you have no desire for going back to your own world because here, there are anime waifu ranging from every possible bust sizes that all falls in love with you.
And their love is justified because your System will, in 3 seconds, grant you super-goku-katana-ninja-samuri-one-punch-god-killing abilities that can easily over power the 10 brazillion years of the antagonist's actual trainings.
That is, as long as you diligently fart 10 times a day everyday to complete the arbitrary daily quests that the System assigns to you in order to gain an unreasonably large amount of exp.
But that's considered inspiring cuz you technically worked for your powers.
So now all you need to do is to wait for the natives of this world to explain you all 3 gazillions of their impossible problems that all originated from this one obviously-annoying-womanizing-smug-dickhead-antagonist, and watch the natives try everything that doesn't work, but still denies your capabilities.
Then you can truly shine as you wipe out all those problems with a berp, dropping the jaws of everyone who had ever doubted you, and soak in that admirations from your waifus.
You can now proceed to do squats over the obviously-annoying-womanizing-smug-dickhead-antagonist's face.
He watches as one of the jade-like-beatuy anime girl, that he was after, now happily joins your harem without you ever even asking, despite the fact that competition to be the best girl in your harem is now harsh enough to trivialize the Ivy League NBA MCATs written by NASA.
Repeat for 300 more chapters until happily ever after or something something THE END
Sounds pretty generic. It's fun to read, but when it's repeated this much, it gets boring as you recognize the pattern, the story becomes predictable, and you lose the fun. When stories in this trope is done right, to me, it's when they put their unique twists, and actually writes a proper story with a beginng and an end, rather than just a dopamine-triggering power fantasy brain vomit.
