Yeah actually that logic flies pretty well in this case.
Nah. Because literally nothing you've said actually counters anything I said at all.
Even if you want to argue that the story started to move into that sort of thing in v0.9, that wouldn't really alter the fact that you had 8 updates prior to lull people in and create false expectations. Hence why people may have gotten invested in the game while thinking it was one thing, only to object when it seems to be becoming something else.
It's not really the moral obligation of players to do homework and research what sort of games the dev has made in the past. Partly because devs don't always make the same game over and over (which means past games don't always indicate what future games are going to be like), but partly because it's generally the responsibility of the dev (or others who are in the know) to make clear what sort of game a game is (which is why the Genre and Developer Notes sections exist in the first post of most threads). If that hasn't been done, or it's been done deceptively, you've got no real ground to stand on to complain when people get annoyed that they feel like they've been misled.
You yourself have pointed out that the tags were edited, which itself is indicative of bait-and-switch. Or at least a significant shift in expectations mid-stream. People who came in before certain tags were added are completely justified if they feel like they were misled. There's also the fact that the tags are fairly vague, so
how they apply isn't necessarily clear. As an example, the presence of "rape" and "violence" tags doesn't necessarily mean that every scene is violent or every sex scene is going to involve rape. As people have pointed out, while the character and the story have always had elements of violence, for most of the game that hasn't really been the case for the relationships the main character has with those closest to them, so that's a change in tone. Which is what they're objecting to, after having played multiple updates beforehand where that wasn't the case.
As for the other part, people have literally complained that they
weren't taking the darker options and still getting excessive scenes. So it's not just a case of picking the wrong options and suffering for it. You'll notice multiple people are basically saying it seems like the choices they're being given are either between "bad" or "worse".
So, you know, regardless of whether
you personally agree with them, they're still fully entitled to complain, especially if they have been following the game for years.
And all of that doesn't take into account the fact that "if you don't like it leave" has always been terrible advice for most facets of life, because without criticism nothing will ever improve. And creators may wind up left with almost no supporters and never understand
why people are being turned off because no one ever says "Yeah, this is the problem." Telling a creator when they've done something people object to is just as important as praising them when they do something people enjoy, because it's how creators grow as creators, and produce work worth experiencing.
So yeah, that logic doesn't really fly.
