Unfortunately, there are a lot of dumb people out there. The hype train is the social aspect, all the speculation, all the rumor/leak hunting, all the cheesy topical posts i.e. "what's the first thing you'll do ingame" that is usually popped by the reality of the actual game, the uneven pace different people go through it, and of course spoiler dodging.
But my point is there usually isn't ant prelaunch buzz for ero games like there often is for major SFW games, and in all fairness I guess there's a lot of people out there who would consider us eagerly waiting for a pron game stupid too. For the record, SFW indie games are also just as quiet. There wasn't nearly as much buzz for BG3, Expedition 33, Balatro, Lethal Company, Among Us etc until after their release and these are considered indie pillars now.
Anyway, I don't think we need to worry. This was the same for many games that would eventually go on to be mega hits in the porn games scene.
