Returned Madness Returns for Two Worlds 2. Apparently there's absolutely no limit on how many times you can recycle your game (as long as you use the credit to buy another game that's on the list), so go nuts until the 27th, Canada.
I will buy Madness Returns when it hits $20. And I don't mind buying it used because I'm a dick and redeemed the Alice code in the game I 'bought.' I have half a mind to see what other games in the list have some sort of new buyer protection (like Mortal Kombat) and get new copies through this promotion, redeem the codes, and then leave myself completely free to pick up used copies later on. There's really no reason not to, if EB Games is letting me do it so easily.
edit - I also picked up a new copy of Twilight Princess for the Wii at HMV, incorrectly priced at $10. It was one of the regular copies, too, with a metallic tri-force, not one of the player's choice editions or whatever Nintendo is calling them. Beating Ocarina of Time 3D made me want to revisit some recent Zelda games, and although I own the Gamecube version of Twilight Princess I've never spent a serious amount of time with the Wii one. I hope I can get over the waggle in favour of having widescreen support.
