My alma mater MMORPGDot has a review of the 'adults-only, subscription-based, independently-developed Sci-Fi Fantasy MMORPG set in London a hundred years from now'. It's a social MMOG, and one with more social options than you'll find in most commercial games
. From the article: "Sex is not a mere role-playing concession in Sociolotron; it is a fully-baked and detailed gameplay mechanic. Players can engage in both consensual and forced sexual relations with other players and some NPCs- and believe it or not, sex serves a number of important purposes in the game. (Aside from the whole heir thing, the fluids that are exchanged and spilled during sexual encounters are critical components of some potions, and the game provides a variety of methods for collecting these substances.) Sex is really a sort of minigame in Socio, and before you utter the words 'Hot Coffee,' understand that this is no mere rhythm exercise. It's actually so complex a process that I'll only touch on a few details here."
