I just finished the Call of Duty: Infinite Warfare campaign. I felt it was positively gut wrenching and one of the best campaigns they have ever produced. I reflected on how poorly the game performed market-wise (at least by Call of Duty standards) and consider myself lucky to have even been recommended the campaign to begin with. Otherwise it likely would have been a great and well crafted story I never got to see.
So, I was wondering, what is one great single player experience you feel may have been overlooked or quickly forgotten? Whether it be due to it being a minor part of the experience, or simply being lost in a flurry of other releases.
