A lot of the outright-rejected suggestions end up clashing so hard that they come off as "can you stop doing it the way you want to and do everything you can to cater to me? For free of course". Writers have a diva streak (and rightfully so, it's a lot of work and you get attached to things you create and if someone wants to tack on something you feel goes against the spirit of your work there's reason to be upset) by nature but Savin is usually open to inclusions and ideas if they're not asking for something he or the staff don't have any interest in doing - like pregnancy content for his characters or player centaur content - or for something he specifically forbade (most of which have a reasonable explanation).
If anyone on the CoC2 team comes off as completely up their own butt it's the Observer. Nevermind whether anyone thinks it's good or not, his content isn't even structured for a game where players can actually play with it. It's scripted from start to finish, disregards every type of player that he didn't envision, and developments don't even lead to quests and stuff, they lead to...more scripted scenes.
Take Garret. He's got several exposition-laden to the extreme follow-ups to his initial quest that let you know in the driest and bluntest terms that he's not getting on well with daddy and wants to get out of the house. In a game you'd think oh, this must be a trigger for a quest that continues his story! Maybe I can take him on a little adventure or find something for he and his dad to find common ground on.
Nada. It's one of several of his in-game novels that the player just...watches without reacting to or getting involved with.
On top of most of his content allowing for little to no room to approach it (at all, like all the passive Garret scenes that go nowhere, or just in any way that isn't how he intended for it to go as you can see with Kiyoko - how would she deal with the situation if person who picked up her amulet was female? You'll never know because the content shuts down if you try to do it that way) he also insists on all of it being hetero-only for an audience that likes and expect to see a broad range of het and homo and bi content - or at the very least prefers futas, traps, and so on to be acknowledged. And unlike Savin who generally allows other people to write scenes for his characters he won't let other people write scenes for his characters period. That's how someone who's -really- so anal and controlling that any suggestion inherently goes against their V I S I O N acts.
