I think it depends on age and duties. If you are middle aged and play games thats fine because it is probably stress and there is probabaly nothing better to do.
If you go to school and play 13+ hours of video games a day thats still fine.
I think the line is when you become unpopular with the girls or when you don't know how to start a conversation with statements other than "HEY HAVE YOU TRIED (INSERT NAME OF GAME) I HEARD ITS AWESOME!"
