If I were as unhappy as you sounds in this post I would not be playing this game. You should only play a game that entertains you, on that increases the stress in your life is not good for you. If you have already received your CE box, then put it on ebay, I am sure there are lots of people wishing they had bought it.l If you still haven't received it, just cancel the order and you are out nothing.
In any event you have options; don't sit around being "angry" over a purchase it is just not worth losing sleep over.
GL w/ what ever you play next
