I had no idea there were so many nudity patches for mainstream games. My favourite is these Morrowind mods, from adolescent male fantasies of the female form to the hysterically kinky.
3D Studio Max renders of the female model using the breasts from Sabba's model. 250 more polygons, but definitely worth it.All the mods are for females, unsurprisingly.
Note: pretty much all these links are adult content.
