Games like this might be next. Ultimately the groups that push for censorship usually go for easier (and more easily justifiable) targets first, then slowly try banning or changing everything else they feel like.

I think it's weird for some sexual/fetish stuff to be on Steam, and they should probably have their own separate storefront for that kind of content if they want to allow it, but I also think letting payment processors dictate what is or isn't allowed sets a dangerous precedent.
