Some game on the Amiga where you had to shake the joystick left and right to forward a (filmed) animation of two people having sex.
Later it was "Moist", a text adventure game. That was my way into AIF.
First AVN style game was probably the original Big Brother. Between AIF and Big Brother were...
Haven't actually play that many, but Radiant I liked, and when ignoring the younglings, Proud Father is cool as well. The twins have a nice story, but I would play that one mostly for the sis. DmD is a classic, but I never really got into it. In lewd Island I chose to be a parent, made more...
Thanks
JFI, I also played Lust Epidemic and Treasure of Nadia, which were quite good but again with very little information from NPCs. Without the ingame guide it would be hard to find the right place to go to see the next event in line happening.
Most of the 'games' here are just VNs, some claim to be sandbox when they are basically adventure style games with time dependency, but little guidance, no NPCs to talk to, so I would say they are bad adventure games (if you need to read ingame hints to progress, it's not designed very good)...
I was a bit disappointed that cumming inside would automatically lead to pregnancy. it's not THAT easy. And as much as I enjoy incest stories, the thought of defective genes in kids is not a nice one.
It's a shame this is progressing so slowly. It's one of my favorites (payed on itch). I hope that some day it will be completed, so I can do a full playthrough.
I'm honestly more into nude modeling (Elle Tan, Debora Alta, Katya Clover, ...), not real porn.
Back in the days I would collect everything from Crissy Moran, later Monique Alexander.
Currently I would pick Molly Little, Kenzie Reeves, Lily Larimar.
I think it actually was Big Brother - which is not really a VN.
Before that I played some Illusion games of course, but I mostly played text adventures (Moist, Sam Shooter, Rogue Cop, Camp Windylake and so on).
I think the first pure VN could have been Sisterly Lust or Lewd Island, I am not sure.
