I haven’t had a chance to read them properly yet (they’re longer than I anticipated), but I did take a quick look when I bought them. I loved the first few pages of Stan’s story in particular, since he’s my favorite character, and I loved getting to see more of his backstory as well as some heartfelt character moments (something I always craved more of in the game itself). And I was pleasantly surprised by the light branching - it feels a little weird having a say in the progression of a story when I’m not one of the characters, but for erotica in particular I think it’s a great idea since people often have such different tastes, and this way more people will be able to read a scene that interests them. It also makes for greater reread value than you’d generally expect from a collection of bonus stories, which is especially welcome since this bonus was a little more expensive than most.
I did wonder why there wasn’t more of an announcement when the new stories were released - nothing that I saw on the website or forum, anyway, and no notification from the omnibus app. If I hadn’t happened to look in my “Promotions” inbox, which I almost never do, I wouldn’t have known the new stories existed.
Very light branching. The stories are written in the third person, so you aren’t directly controlling any character. And instead of being prompted to make a choice every couple of pages, you’re prompted to make maybe two or three choices over the course of the entire story. I don’t know that I would really call it interactive, since the text isn’t actually responsive to your choices, but there is definitely branching. Basically, the author wrote three versions of each sex scene and you get to decide which one you feel like reading.
