I use Linux for everything, and Ren'Py is the only one consistently offering a Linux version.
On the rare occasion when it didn't, the Windows client worked surprisingly well in Wine, but I would not take that as a given.
I liked most of what I saw, but was a bit miffed about getting involved with women that I was not interested in, against my will. And the game even asked me, but sent me there anyway.
I tried it and was not impressed. It was like downing a six of hard liquor and getting drowsy but with a sore throat as a bonus.
Sure, if you prefer that then you do you, but I did not see the allure.
Ha, no.
The family I fuck in my fantasy is extremely not tied in any way to the real people. It is a fanfic in my mind, as realistic as if they were superheroes and we lived on another planet.
As for stuff like anal, BDSM, watersports etc. I have tried it and found that likewise it was better...
