What happens if you play too much computer games

This Rarely Happens But...
Playing Way too MUCH will get your eyes into the video game world like GTA but everything is like on whats around you but Video Game World, And Your Brain Will think you can do whatever you want like shooting someone dead! and if your shot dead, you won't come back!
Or
Your Hear the sound for a long time like Beeping sounds, shooting, or rarely, you get ill!
Recommenced --> Play for a hour, then rest for 2 hours from the gaming Then Play again and so on and so on
