I can't answer for Kanisatha... but I would have just left it out. Porn is extremely easy to find on the internet these days. I don't need it in my video games. Put that time and energy to work on more important game systems.
1. The cinematics in the game are very far from porn. 2. Everyone constantly talks about some mythical “resources”; a spherical horse in a vacuum looks more real. 3. Use the censorship options in the game and be completely happy. It has already been implemented. I want to see a full disclosure of relationships in the game, even sex scenes, but I won’t have the “turn on” feature if it’s not in the game.
