Reddit reviews Human Omega: Discovered on the Slave Planet (Pykh Book 1)

I've never read a harem in LitRPG that wasn't flawed and seldom read one that even seemed to try. They tend to be rather lazy paint-by-the-numbers and not even hot.

The best harem I ever read in the genre was the hero's father's harem in the sort-of LitRPGish Isekai Transcendental Misappropriation. I liked that they established harems as a thing in this world before the hero getting one, and liked the exploration of how the harem interacted in everyday life. When the hero got his own harem later in the book things went down hill.

As far as non-LitRPG books,I kind of liked the harem in A Brother's Price. They managed to twist things so the harem was not a manifestation of the hero's strength but of his weakness.

We only saw it briefly, but I liked the idea of the harem in The Broken Crown. The guy in the harem wasn't a character, and the protagonist cared more about her co-wives then her husband. A neat twist, but not what most people here are looking for.

The harem in Savage Divinity never remotely feels like a real relationship or "hot", and is usually annoying, but the author at least gives the members of the harem actual distinct personalities.

As far as what is hot...The reverse harem in the Merry Gentry series was sort of fun. I liked Heinlein's harems in his Lazarus Long books but that may be because I read them when I was going through puberty.

I'm hesitant to mention this one, because it's really more erotica, but the Pykh books at least did something new, and developed the characters more then most LitRPG novels do. (Three people captured by more advanced aliens strike up a relationship without really understanding each other or being entirely clear on each other's genders. It's better then it sounds. But then, it would have to be. It also comes closer to being a healthy relationship then most LitRPG harems... )
