Samantha Fox strip poker on C64, man you needed to wait for the game to load from the cassette tape.
Next was the original Leisure Suit Larry in all of it's EGA goodness. That one can find from Steam, but you need to jump some hoops to change it to EGA version from the VGA one.
Of the more indie flavor of the games first one was Research into Corruption or Cohabitation
I forget which was the first but I think it was Daughter for Dessert. Maybe Milfy City or Dual Family. I know Summertime Saga was in there too. I played a bunch of flash games too, but I couldn't tell you which ones. I know WVM was the one that got me talking about VN's with others and was also the one that inspired me to make my own VN.
As it happens, I haven't played a single game downloaded from this (this particular) resource. I downloaded all the games somewhere else, but not here. For me, this is a backup resource, nothing more.
