Editor's Notes & Price Research
For those that purchase Middle-Earth: Shadow of Mordor Game of the Year Edition, you will also receive Tom Clancy’s The Division Beta & Tom Clancy's Rainbow Six SIEGE BETA (automatically added to cart) for free with your order. - Randy71
Won Gamespot Game of the Year 2014 award and I'd agree with it.
Lowest price I've seen for one of the few games I actually played to completion.
EDIT: Just want to add a note that you receive the Steam key near the bottom of the order confirmation email. The email took almost 10 minutes for me to receive, so don't be surprised if it doesn't come right away.
