It wasn't a great introduction to the idea that sex was a worthwhile subject for videogames. Published by Landisoft in 1985, it was about waggling a joystick back and forth while two bright pink cartoon people went at it like joyless jackhammers. That's literally what it was called: Sex Games. My first experience of that came via Sex Games on the Commodore 64.
But there have always been terrible sex games.
