Awesome deal for me! I had purchased the origins collection on sale digitally at one point around christmas and I flipped the code included for 18 bucks. So I only paid around 3 dollars for GoW 1-3!
Just to butt in, I picked up a copy of binary domain a couple of months ago for this price and I was thoroughly impressed, minus the voice command technology. That can be turned out and it is still an excellent experience!
