Yeah, the blatant corruption and the whole "getting smiles painted on your soul" parts are also a big turnoff for me and something the MGE could do without. I mean, if it's a setting that allows anybody to be happy, it shouldn't force the happiness on everybody. For one, if DE just removes the sexual inhibitions, and turns human women almost exclusively in generic Succubi with no personality changes, it would be far better. But as it is, not really. That's why I also prefer my Mamono born that way instead of corrupted human women, as well as Bright Green Demon realms and pure angels rather than the dark versions.
I also don't see why Incubi have to be a thing. Increased lust and SE production for a man, fine. But having his mind warped and body altered to be utterly dependend on his wife and not able to go ten minutes without sex anymore... As well as having reduced interest in everything that is not sex...
See, a big problem is that KC isn't as good as worldbuilding & consistency as he should be. Too many things contradict his own statements on the matter. Likewise, if he needs to intervene all the time to clarify the setting isn't as bad as he writes it to be, then he's clearly doing something wrong. Also, he can't seem to decide or find a balance between making the setting cater to his own fetishes only, or catering to his audience's desires.
I could go on and on about my hidden frustrations, but in the end I do like MGE. It's a nice escapist fantasy porn. And that's why it saddens me that it's just not better. It doesn't have to be deep, it doesn't have to be thought provoking, MGE just needs to be entertaining and uplifting enough. Because, quite frankly, too much stories (films, series, novels, etc.) lately are dark and depressing. Which someone who is depressed, like me, can do without.
