Didn't the developers abandon Valentina's Story as well?
What are they up to nowadays. Are they working on any other game?
It was one developer, not multiple. He did abandon Valentina's Story, yes. But that was due to copyright issues, or so he said. He had been using copyrighted assets in developing VS, and when he realized it, he decided to abandon the project, rather than try to redo the whole thing from the beginning. He decided that, if he was going to have to start from scratch, he would just start a new project, which is how we got VWA. And VWA was much better than VS, in my opinion.
As for whether or not he's working on anything in the gaming industry, who knows? If so, it isn't anything in adult gaming, or at least not under the DRG name. As far as DRG is concerned, he's completely disappeared, and it looks like it's a permanent state of affairs.
