Well I was throwing away some old PC Gamer magazines the other day, and noticed a few of them had some loot codes.
The first is for Guild Wars. This item is for the miniature Asura pet.
"To unlock: At the log-in, click "Create Account or Enter Access Key". Enter the code. Type /special in the chat panel, Retrieve the item."
Next is for Lord of the Rings Online. The 2 items are The Fallen Star of Gil-Galad, and War Cloak of Isildur.
Says to visit www.lotro.com/pcgbonus
, but that link doesn't work anymore, so that code might not be valid anymore.
