not that much of an isekai expert, but making good stories would probably require straying away from the power fantasy elements and focusing on the feeling of being alone in a new situation that everyone takes as granted.

and i can't think of a better way to alienate the (generally) weebo viewing audience than saying 'you, the hero, are less equipped than anyone else to deal with the adventure of being an adult, and you're clueless about how people act and behave in real world'.
