FOBS felt like an experimental project for Zell; it was a place for him to try out ideas and funnel some of his passion for the genre. It got a lot of attention and so he's decided to try making a profit out of his talent. Who can blame him?
I'm glad for the content we got (and continue to get, albeit not as often) for FOBS; Zell even provides direct downloads for the latest, English-translated versions on his website. I personally hope all his projects do well; man's got talent and I'll be happy for more of his content, paid or not.
That said, has anyone heard anything about Succubus Affection? DLsite claims "early March" release, but here we are and I haven't seen anything new. Also, can we get a dedicated thread for it? We're often talking about three different games in this thread alone.
