This is a lose 50 experience moment.
TL;DR: Move on and find another project, this one is already dead.
Eh. Respectfully disagree.
JoohJooh's made it fairly clear that he's treating this game as kind of a learning experience. He's doing what he wants and experimenting with the process and his own ideas as much as seeing how the community reacts to them. I don't think he's comparable to a conniving GM, I think he's wading into the salty waters of H-game development and tripping on sharp rocks or angry crabs here and there.
The guy churns out updates every two weeks. I wouldn't call that "dead," I'd call the big games that go ten months or more without new content or at least posting status updates and teasers "dead."
I think the problem is that...well...that's kind of all there is. Without an attachment to the characters, a story to progress, or things to achieve in the game, we just click through the porn, shrug, and get back to whatever else we were up to. And then it feels like there wasn't really an update even though we'd just played it.
Padding the runtime (though not to the point of excess) with quests, searches, or combat would ironically make it
feel like more was done because more time would be spent getting to that content. ConQuest had an update recently--if you took the combat out of that game, how much fun would it be?
Game's not dead, it's just slow because the dev is figuring out how to make the game he wants.
...but you're right, writing has gone downhill pretty much everywhere in the mainstream. To find good stuff you need to put in some legwork, find discussion groups that aren't just echo chambers or circlejerks, and learn where to find self-published works that don't get much advertising. And even then you wade through those to find the odd jewel amongst riverstones. If nothing else, you can find old stuff you've never heard of that's at least decent.
