Well, no, the reason for that rule is so that people who want that content, won't find games with those tags, play the game for that kink, and not find anything they wanted to see.Eh I don't really think it's worth it or that it's a big deal. The game probably will have cheating so I don't really see the point in removing it. The whole rule about not including planned tags is because ideas for those tags occasionally get scrapped or a game gets abandoned before making it that far.
I agree, it will probably be added for Gretta (at least I hope so, more fun rubbing it in his face that way), and in theory someone else, like Simmone, could end up with a fiancee promised them before it's over, and now that I think about it, wasn't Holly engaged to Waldo at one point in her story? Maybe that is what they are counting?
