Superb question man, this really goes toward people forcing video games to be part of them every second.
If so, that would be tremendous sometimes because on certain days we need to exclude ourselves from everybody.
They would be bad for you if you play them for long periods and are not interesting in: resting your eyes, sleeping, eating, etc.
That is a great question and you have to be careful what you play; this is mostly with mature games because some of the aspects can be controversial.
