I know what a creative vision is. I understand that BaDIK is something made by one man with a specific vision. He knows the story; he knows the characters and game mechanics more than anyone. I don't want to be the person who wants to tell him or anyone that I know those characters or story better than him. And I don't think he should listen to people who do. But your line of thinking looks like a complete rejection of constructive criticism and objective flaws in the game just because it is successful. How can we have an objective flaw? Because we're talking about writing, there are writing principles that make a story better or worse and there are some writing errors like plot holes.
I don't reject criticism as is, but here we come back to what we have already discussed. Fair criticism can be called what the absolute majority of players do not like, so it deserve critics and should be fixed somehow, probably. But do you have such statistics? I don't think so. Does it or would it interfere and conflict with authors vision on some aspects, characters and plot development? And finally, this game is not complete, it's still in development, and, probably some things you are not satisfied with currently may change in near or far future.
And finally, some criticism just can't change anything even if it's fair. Like development time increase or DPCs approach to development and other mostly philosophical questions.
My points why DPC shouldn't be criticised and should be able to peacefully release his idea in a final product:
1. He work and create game alone, not in a team. It changes a
lot. This guy is crazy, in a good way. For this alone, he can be forgiven a lot.
2. Story and game itself is not finished, yet. What you criticise or have a wish to change may be implemented later.
3. Almost each player, including AVN addicted ones, got a lot of options and choices which fits their taste and preferences. This can't grow infinitely, but I think nobody may tell that BADIK have few options or most of them are fictional and fake. Just correlate your wishes and expectations with reality and compare game from time to time to other ones in genre to stay tuned.
4. Make sure what you exactly criticise are really not liked by a majority or at least a lot of other players, otherwise it's your personal trouble and vision. Think of what and how game would change if your wishes sometime will be implemented.
5. Call me any other game (in same genre, of course) which have 12k+ pages of discussions on a single forum. Look at the game rating in Steam, as well. It's a quite decent and fair indicator of game quality. Games which have really serious flaws or the reasons for criticism doesn't have such ratings.
I don't forbid or dissuade anyone from criticism, but since you are for justice, you should be aware of why this is impractical and useless in the case of BADIK and DPC himself.
We are all here thanks to his idea, realisation of such idea in game, and all these discussions and battles are just an indicator that the game and product itself is doing well. My opinion and my 2 cents
