I am a first time poster here, and just wanted to say that I agree that this would be an instant purchase for me if the expansion was included - even if the game was bumped up to $9.99. I already have the original on disk and copies seem pretty easy to come by in the wild at Goodwill and the like, but I have never seen a copy of the expansion. I love GOG and have bought other games here, but for me the availability of the expansion makes or breaks the purchase of this game for me. I'm hoping there isn't some kind issue with the rights to the game preventing you from offering it, and that you are working on adding the expansion at a later date.
