In the United States, if you buy both Pokémon Omega Ruby and Alpha Sapphireat Toys RUs, you get a Charizard plush.
In Europe, a GAME or Nintendo UK pre-orderwill net you a nifty tin case and a little toy when the game releases, November 28. I think Europe got the better deal, unless you must have both versions of the game and need a throw pillow or snuggle buddy.
