I heard a lot of people had all kinds of issues with either not getting the game, or not getting the Slime plushie, or both. I think its so funny how they thought it was ok just to cancel my order without even telling me. I am glad I am getting the game through Amazon anyway because its cheaper, free shipping, and it wont be opened by a Gamestop employee.
There were a bunch of these Slime plushies for sale on Ebay starting last week before the game's release, which leads me to believe that Gamestop employees of the stores got the Slimes early and started selling some of them.
