I kept illegal in quotes because it's not really, but your comments and entitlement bring a lot of things into question...
1) Okay, so you knowningly didn't get what you ordered, but you still opened it because?
2) You keep calling it a mistake on their part, like this is some malicious move against you. It has the same sku number... it's an honest mistake that could have EASILY been corrected with you simply returning the game unopened and picking up a genuine LE off the rack.
I can come up with many more, but I rather not debate about this. The long / short is that the sku number is the same and you shouldn't have opened the game. Even when BB comes to you with understanding and is nice enough to attempt to fix the error, you instantly act like you're entitled to coming out with 2 copies of the game and life is great.
My order from Amazon was .5 lbs and was the Limited Edition.
