I have to agree with a mandatory "planned" tag list, or at least something like "tags that will never be included", so people can at least know which games they might not be interested in, appart fro mthat, in my opinion, a dev that doesn't know at least the tags that the game will include, just tells me that he doesn't have anything planned, has no objective for the game, and doesn't know what will happen with the game, which screams abandoned game if you ask me.
As for your view on "weak-minded" people, I suppose I'm weak-minded for not having the same fetishes as you, or as everyone else, I don't care if a game has, for example, femdom, but I don't like it, so if in the taglist it says there is femdom in the game, and I don't know if it's avoidable, why would I play a porn game, about a fetish that I don't like, or in a case of a game like this, that might have some NTR, if someone doesn't like that fetish, why would they lose the time to follow it until the dev decides to add it or not, that's why up to a point, I agree to have mandatory planned tags, there is no need to have them planned and writed on stone, but as a dev, knowing what you want to include in the game, and have at least an almost complete idea of what the full game is going to be, should be a requirement, you may change it down the line, but some lines should be followed, if not planned properly, there is no way something as long as making a game is not going to end up going wrong, and the amount of abandoned games in this website, shows that perfectly well.
Appart from all that, knowing that this dev has 2 abandoned games, 1 of them being remade, and now this one, can't really say I trust the dev to go anywhere with this one either...
