GOG.com has just released a compilation pack for Leisure Suit Larry for $9.99 -- it comes with Larry 1-6and Softporn Adventure. This is a compilation that originally came out in 1996 (RIP Sierra), but now it's available in digital form, free of any DRM, in typical GOG.com fashion.
Of course, as is the case with anything Leisure Suit Larry related, the trailer may not be safe for work. Oh Larry!
I still remember sneaking into my uncle's basement during a family reunion as a kid once, while all of the males in the family were huddled around the VGA version of the original Leisure Suit Larry, laughing and having a good time. They turned around, saw I was there, and invited me to watch with them -- I felt like a man.
