Is it weird to say I want more Kiyoko, like her getting thiccer and bigger tits if you keep giving her more kids even after bringing her back to the world?
Also, Observer is an idgit if they think we're not going to go back to the game's hyper-sexual ground-state after the chance to be a father to our named daughter is ripped away from us. Of course we want to fuck Kinu once she's all grown up, we don't have the bond of her being our daughter because that opportunity was stolen from us by plot contrivance, same as Helspawn before her.
Over all, both TiTS and CoC2 seem to get bogged down in adding side content for months at a time while the main plot is put on the back burner, getting few if any working hours from the team. And while that side content can be fun, often some of the most fun stuff in the games, it feels like the main story should get finished to a functional state before most of the side quests get fleshed out.
