I infer from your comment that you are not a manager. To (good) managers, knowing "how you are" is critical. As a manager, there is nothing more important to me than finding out if my reports are sad, annoyed, tired, frustrated, all of the above. Especially in a work context, it is very important to make sure people are happy with their job, or find out if something bothered them in the past few days.

On the other hand, why would they care what game you played last time? They are specifically asking a very open ended question and counting on you to be a professional and share with them what matters to you and affected your mood.
