Yeah, Soft Porn Adventure WAS included in the LSL Collection. Plus you can find it on sites like Underdogs. By today's standards, it's very simple and short, but I hear back in the day it was quite fun.
And look at the price, people! $30 for a Atari PC game over 20 years ago! Considering you can go through the whole game from start to finish in 15 minutes if you know what to do and factoring in inflation, and games were more expensive back then.
But that's AWSOME trade bait. I'd start the bidding at $100 on EBay and see how high it goes up. Plus it looks minty fresh and in great shape.
Plus the current EBay auction is for the Apple II version. The Atari one may be a bit rarer.
Sierra in the early 80's (known as Online Systems) was a very small company, like Activision and EA were when they got started. I'm not surprised Roberta decided to cut costs by saying 'hum, we need a adult picture for the cover of this game.....I know, we'll use my hot tub and borrow a couple of people! Heck, I'll get in also, to save money.' If you've ever read any of her interviews, she's a smart, funny, and all around nice person.
Plus she also lent her voice for some of the later Sierra games, such as King's Quest V.
And it was'nt just her that was in her games......Jane Jensen, another one of the brilliant designers that Sierra had during it's hayday (Quest for Glory series, Gabriel Knight series, Phantasmasgoria II) is in some of the scenes of Phantasmagoria II -- in a S&M club, no less!
