CymTyr: The first person to reply with the game I wishlisted back in 2008 upon joining the site will receive an Origin key for Mirror's Edge.
Hint 1: The game is not on GOG, but will be soon.
Hint 2: The game came out in 1988.
Final Hint: The game is squad-based.
BTW if you try to find it in the wishlist it won't be there. It was removed when a newer entry for the same game was made which received a hell of a lot more votes than the original listing (mine), and mine was flagged as a duplicate.
EDIT: As an added bonus, I will give you a Populous Origin key. I already have it on GOG.
Edit: I hadn't scrolled down to see other replies yet but had to answer this one anyone.
