I think that, if I am not mistaken, graphics are going to become more realistic in gaming and virtual worlds. Right now there is a cartoon-ish/unreal quality to the graphics.
What happens when the tech becomes better and the line between fantasy and reality blurs? For some, this will be the case.
They have shown that porn can insight rape, and unrealistic views, of women. How will interactive rape sims have an affect on certain individuals?
I saw SL as a beacon for the advancement of positive/creative immersive places. There are some amazing, inspiring sims out there - and amazing creative people. In with this is a mix of destructive/debase sims that hold NO candle these spaces, in my view.
Maybe LL, as well as creating Patterns, should develop a separate world for the more 'perverse' RPG ideas - tap into that market - and keep SL more 'mainstream' and inspiring.
I am NOT saying people should not explore rape sims - that is their freedom - but I think that it is a fetish that appeals to a tiny demographic and is of no real interest to the vast majority of people - hence promote it as such - and keep it out of the main login page of SL - simple.
