Seven Realms was a really pleasant surprise. Story-heavy, with great renders and very enjoyable sex scenes with animations and everything. On top of it, it's a harem game, by far my favorite genre.
The premise of Seven Realms seems to be more or less inspired by World of Darkness (have you ever played "Vampire: The Masquerade"?). Here we live in a world where vampires, werewolves, demons, fairies, and whatnot are real, and they each have their own "realm" (thus the name of the game). We take control of the protagonist, known as Atlas by default, who is a vampire and heir to the vampire realm. The story begins with him meeting a woman named Leyala (who is the "main girl" of this game), who has a mysterious "connection" to him and has people trying to kill her. The plot then sets off with Atlas trying to find what Leyala really is.
The world-building of this game is handled and presented pretty well. Also, the protagonist has his own personality and back story, whereas the game still offers you plenty of options to choose how you want him to act in various circumstances. The love interests are likable with their own personality and background as well. Atlas clearly favors the three "main" girls of his harem, but here's hoping that he eventually has further character development with the other girls as well.
Sex scenes are not scarce (yay, not another "blue balls simulator"!), and as I mentioned, pretty well done. Plus, they get significantly better as the game progresses, with all scenes fully animated. The game offers a good balance between plot and adult content, which is always welcome. Regarding the content of the sex scenes, it offers scenarios of the protagonist with one of the girls, as well as group sex of the protagonist with two or three of them. It doesn't really have any extreme or unusual fetishes that could throw some people off, with the optional patch that allows having threesomes with two (non-identical) twin sisters being maybe a notable exception.
All in all, I recommend this game. Interesting and unique in its own ways, the writing truly caught my attention and didn't make me want to hit the skip button once (and I do that pretty often).
If you like harems, vampires, World of Darkness, and AVNs with fantasy settings in general, you might want to give this one a try.
