Oh, damn. I heard about this news getting on Steam few days ago but I skip it as a mere, "nuh uh, it wouldn't affect me since I don't play those games." I forgot to realize there are games that have adult content as theme, not as hentai. I should think about the implication like what Emma said ...

A lot of Interactive Fiction was affected, not just THOSE games. And with the vague terms, they can go after many other things. They basically have made is so that if any special interest group/activist group lobbies the Card Processors cause of something they don't like, they can shut said thing down. Soon we won't be able to play Horror games...or anything with Violence...etc.
