Yes, if you are talking about AVN: Leap of Faith, Sisterly Lust, Being a DIK, Acting Lessons, Lust Theory.. including the DLCs for those that are available, those are the ones I have purchased so far...
So far, so good.. only played about 20-30 minutes worth, but interesting so far ;^)
(PLEASE check on GOG though, I think you will be surprised at how many of us are willing to purchase through them to support you guys/gals (DEVs)! Even if it is free download!)
Many of us prefer GOG because of the DRM free (no internet requirement, and tracking) ability.. STEAM has DRM, and requires an internet connection on many, if not most, games.
BTW, I had downloaded each and every one of those I listed before I purchased them. After I had seen their quality, I then knew the DEVs deserved to be supported. (I am also a Linux user, and fully support this type of system.. good coders deserve support (and respect).)
(P.S. Less than 4 hours since I posted the original and I already have +1 (the second was actually from me.. was testing if I could count on my own post, apologies)...)
