Yeah I'm aware, I honestly don't think the server is bad, you can have some meaningful conversations there and all, though I must say I do prefer foruns since it's easier to catch up and stay on topic, but the cultish nature it carries around bothers me a lot and I do believe that toxic positivity may lead to many bad decisions.
The game does make bank and as said Sel's work ethic is flawless, but I truly believe he wouldn't feel as ostracized on the VN community (like the VNDB incident) as he does if he listened to some constructive criticism, QOL changes is neither hard to implement nor does it harm the game design. Although, yea, to be fair, in that particular incident some people were just assholish for the simple fact that the game is based on KK.
