Can someone re-explain what was the involvement of "sakibus diary" and the development of succubus affection? Was he/whoever they are, the other person that irc some people here said insisted for a more maledom approach to the game, and how much was Zell involved?
I could be wrong, so take what I say with a grain of salt.
IIRC Zell did the art for Succubus Affection, and Ansala (I think that's the other person's name) did the programming. Ansala is more into maledom than Zell is, and so pushed for that to be included. Shiro no Yakata is going the same way, I believe, with Ansala coming on board to help Zell out with it. Which is why Zell is making another game along the same lines of what Shiro no Yakata was before Ansala joined up. Don't remember the name of it though.
Zell ended up burning out with FOBS a while back due to needing to actually program it, and not having much fun doing so. He took a break from working on the remaster to focus more on Shiro no Yakata, then came back to FOBS fairly recently. Now he's working on it fairly consistently, along with juggling Shiro no Yakata (with Ansala) and his other game. At least, from what I remember.
