Depending on how you view a game may be a form of play. And according to Brown & Vaughan (2009) play has the following conditions:

Apparently purposeless (done for its own sake)

Voluntary

Inherent attraction

Freedom from time

Diminished consciousness of self

Improvisational potential

Continuation desire.

A game would have the above conditions but would be more rule based over the improv design.
