I already read most in your list... except perhaps Desolate Era and mecha otaku. Is mecha otaku better than knight and magic?
It's the same thing. I just like renaming things, my bad. And that's where I'm going at anyways, most of the stuff out there are fairly common. You took down a whole chunk of it through harem and revenge. That aside, I took out the Chinese section as I usually read raws and I got a much larger variety where I'm not subjected to overly hyped novels. If you want to read to start trying to read Chinese, I will pull out some for you.
I have absolutely no clue~ I'm bilingual with speaking it while learning to read most of the characters through watching drama with subtitles at night and turning the volume super lower so my parents couldn't find out. Sorries. xD
Your reading list isn't publicly accessible, so not sure what you've read or haven't read, but it seems like you've read the majority of the male MC reincarnation stories. However, there's bunch of female protagonist reincarnation / new life stories which might be worth trying out. Mei Gongqing A Mistaken Marriage Match - A Generation of Military Counselor The Strategy to Become Good at Magic Descent of the Phoenix (I'm including this for reference, but I don't really recommend it all that much. Starts off good, but then gets generic) To Be a Virtuous Wife There's also a number of otome-game reincarnation stories where people get reincarnated as the villain characters and must somehow avoid death flags if the heroine wins: I Reincarnated into an Otome Game Villainess with only Destruction flags An Otome Game's Burikko Villainness Turned into a Magic Otaku Akuyaku Tensei Dakedo Doushite Kou Natta Villainess Brother Reincarnation Tensei Oujo wa Kyou mo Hata oTakakioru It Seems I got Reincarnated into the World of a Yandere Otome Game Kenkyo, Kenjitsu o Motto ni Ikite Orimasu
Have you tried Dominion’s End? It is about a woman from zombie apocalypse world, that died because her partners betrayal. Her regret is that she depend too much on her partner and didn't strengthen her self. Then she wake up in the body of teenage boy, several days before the zombie outbreak began.
I've read around half of Japanese one and one of the Chinese. I'll take what I haven't~ thanks~ It's not that I didn't make it public--I haven't even make my reading list... lol sorry...
