Yet Jenny, Debbie and Diana still received some new content and sex scenes after the ban. (i think) But if I were in DC's shoes I too would be very careful playing with potential fire. So I don't really see the lack of incest content as egregious as some ppl on this forum do.
Yeah, as you say, I wouldn't even call it a lack of incest content in the first place. The game by now has the amount of incest content it is supposed to have. Jenny's content is just done, while Debbie will get a rework and pregnancy and Diane is supposed to get a few additions here and there.
And that's alright, but there are too many of those other characters. The most core characters still didn't receive their deserved conclusions, yet there is still a constant influx of new faces, new plots and "checkhov's guns". You know, at some point I wanna see how the story ends and preferably before my children get to have their own children.
To me it's really not such a big issue. Sure, the main story added too many of these characters, but it's not like they take thaaat much screen time and the main story updates certainly needed some girls. I doubt people would have been happy if DC had spent months of time on releasing an update that would have consisted of Raz, Dimitri, Igor and Jab.
These secondary/tertiary charaters are hard to judge in general, but I think game would be worse off if we didn't have characters like Odette, Liu, Tina, Maria, etc.
It's a fine line to walk and at least the main story certainly got closure, now that DC added the final scenes in these pre-tech updates and I think those who play the game in the future, won't mind them, either. They are honestly only "bad" for those who suffer now, because it takes time to finish the game.
The family are the first characters you interact with, they're the first characters to have had any lewd content when polling wasn't even a thing, the intro of the game pretty much states you have to be the man of the house because your father died and also get a prom date, the main quest revolves around finding out what happened to your dad who is family and is obviously related to Jenny and married to Debbie, IIRC Diane was the first to get a dedicated quest.
Sure, they were never meant to be the main focus of the game, but you can't say they don't play a fundamental role in the game.
The point I wanted to make is, that SS was never advertised as some kind of real incest game. So it's not like DC promised to develop something like SnowDaze, where MC fucks his family and that's it and ended up producing something entirely different. The game we get now is essentially what DC promised we'd get.
I mean, MC is a school boy who lives at home with his family, so it makes sense that this is where the game starts. Sure, it did play a (significant) role at first, but that doesn't mean that DC had to change his plans for the game, just because people liked some of these characters a lot at first. Jenny, Debbie are simply 2 among 8 main girls, while Diane is a strong secondary character like Maria, Mrs. Johnson, etc.
