Holy crap. If you haven't played this game, do it. It's the full talkie version, and it looks like it is only a 370 MB download.
Great price for a great game.
Looks like Activision (which owns Sierra and it's back catalog)has struck a deal and will be releasing more games on GOG.com. Awesome!
What is weird, is that it says it is rated T for teen, but I'm pretty sure it is a mature title, lots of blood, and some R rated swears.
