Steely_Gaze: Giveaway is official done with this post!
Lemon_Curry: Would you be so kind as to tell us the correct answers?
I'd rather not list who won without their permission, although Duragon did post, so I feel safe in saying he won the randomly awarded copy of Postal.
In any event, the first game I bought on GOG was, as many successfully guessed, The Broken Sword 2. I'd always owned the original, having bought it a department store closeout sale early in 2000, and when I first signed up with GOG, I bought the sequel without delay.
As for what I bought over the weekend, I chose to purchase Anvil of Dawn and the cel-shaded Prince of Persia.
