How long should my child be allowed to play computer games

Believe it or not computer games are actually good for you in the short-term.

However, after about 30 minutes problems can arise and many children (and adults) become almost addicted to the game, having to get to the next level, and a major tantrum can follow an instruction to save the game and switch it off. It would seem that an area of the brain that may struggle to hold attention in the classroom, can hyper-focus when gaming to an almost obsessive level. Therefore, it is best to set a house rule regarding the amount of time spent gaming. This is not going to make me very popular but I would suggest 30 minutes maximum.
