If the official really joined the dubbing, you can generally set the dubbing volume in the settings. If you don't like it, you can set it to zero directly.It will be a great joy for people who like to have voices, hahaha.
I'd also like voices but I think that's best suggested for a future game. Implementing it now while it's in progress would make things slower & not to mention the costs & time to find fitting voices for each.
Hmm....it's 50/50 for me. I mean I would love to hear voices in the sex scenes and what-not but on the other hand it could turn out really bad and really ruin the avn so it could go either way ^_^
