I had been playing this game when I was younger and thought of starting again. Looking at other game-hosting services, I found the new "HD-version", but before I considered buying it I discovered it does not include the two expansions which I found a bit disappointing. Therefore, I decided to join GOG since I read that you could find the game here, without HD, but with the both expansions. Now I will try to find a HD-mod for this!
