I'm a little "worried" about the future "fetishes". Not the fetishes by themselves but the devs commitment to their initial ideas and doing what the fetishe mob asks for. For instance, I've playing a VN from the start and the dev always said that it wouldn't be harem but suddenly, out of nowhere, my LI tells/asks the MC, that she loves, that she doesn't mind if he fucks her friends that she just met. Let's just say that it destroyed my LI in that entire story and the hours of playing and years of waiting were wasted. It wasn't well thought at all and it was horribly executed. It's just one example of many, one that will Sadly keep me away from playing it again. Then there's other devs that are like: "oh I didn't included some tags so there wouldn't be spoils" and adds tag after the update spoiling it for the people that will play latter... Me? I just 1 star review them for wasting my time.
Sorry about the rant but I'm sure you agree these are valid concerns and Devs should try to stick to their original tags because that what makes many of us decide if a VN is worth our time and support or not.
