Most animals do play. Games have a function, which is basically training: fighting another male, hunting, fleeing... Some video games can have a similar function. Not to train you physically (although a 'dumb' FPS like W3D can do some good to your eye/hand coordination) but mentally. How to react to pressure, how to react to provocations or even insults, how to lose gracefully. It can also be good for your cognitive abilities. For instance card games can help with training kids (lots of additions and subtractions).
