Also of note, Interplay is having a 50% off weekend sale there (ends at around noon on the 16th). I got Earthworm Jim 1+2 for 3 bucks. I'm debating on picking up the Descent series. They are only like 3 bucks per game.

I imagine that if Jazz were to be released on GOG, it would be priced about the same
6 bucks for JJ1
Maybe 10 for JJ2
