Dude. That shit is excellent.
I rarely ever comment or review games I play, but this is one of the few that I feel deserve it. There is one thing that game has that very few others, if not none, have.
I'm not talking about the art, the scenes, or the great amount of content. While these are very good and would deserve their own review, what really surprised me was the actual world. The person that made this actually took a deep breath, sat down, and seriously gave thought on how to make an interesting, unique and coherent universe with a gripping story. There are factions with their own characteristics, environmental phenomena, different cultures, etc. This sort of background detailing is something very few porn game developers even try to achieve, let alone do so successfully. While further character development seems to be still in the works, the world-building is already much more than anything I've come to expect from a h-game. There is a legitimate, fleshed-out lore in this, and I found myself actually going out of my way to learn more about it. There is literally a room that lists a bunch of stuff about the background and environment, each entry with detailed descriptions in a diary-styled fashion.
In short, this is one of those rare h-games where you keep playing even after busting your nut. This is a typical "Came for the porn, stayed for the plot" situation.
