@Acolytus well, I'm pretty sure there are multiple isekais where they take up a ruling position and have to deal with very delicate politics. Any ruling power in whatever era has to deal with delicate politics. But the majority of these isekai series don't execute it well or rather brush over it...
seriously? killing the dragon who is here for revenge and saving the humans with evil intentions? "These guys have families too" okay but does the dragon not have a family or home that these humans destroyed? pretty stupid
on the other hand jealous mother in law goddess is pretty nice
