Like FIFA, Madden, Football Manager and WWE 2K games, Call Of Duty has ascended to a kind of brand permanence that means it will sell every year no matter what they do with it. They can move as far away from the original concept of a historical war epic as they like - even jumping to space and cyborg warfare - and fans will still flock. Luckily, they usually know exactly what they're doing.

But ignoring every release is doing the franchise a disservice, because it's a mega-brand that deserves to be considered for both its merits and its failings.
Now that Infinite Warfare is out, this is the perfect opportunity to look back on the longest-running, mega-selling warfare franchise to work out exactly which titles deserve the biggest bragging rights.
