5 Game series that have lost their way

Yes, we know this is a controversial one. But when a multi-billion generating shooter series serves up a game every year, it was only a matter of time before the gameplay and multiplayer began to feel a little bit stale. In fairness, Activision has a tried and tested formula that should see the latest CoD sell in its bucket loads once again. But is anyone excited about CoD any more?

Where Battlefield 4 promises some interesting new single- and multi-player elements that could help lure CoD fans away, Call of Duty: Ghosts has a dog. Well, pooch or no pooch Activision is going to be wagging its tail all the way to the bank whether the game they deliver is as ground-breaking as Modern Warfare or not.
