I do not know if they have it everywhere but at least in Europe there are warnings on the packets of cigarettes. They say thing like: Smoking is deadly. Smoking causes serious damage to your and others health and that kind of stuff.

I am starting to believe that those kinds of warnings should be on games too. have you heard of FPS doug. He is totaly sick. You can see him on youtube. This guy is nuts. Or see this film of a German dude. He is totally freaking out:

I think there must be warnings for that. E.G. This game can be frustrating and cause hart attack.

or This game is highly addictive and can couse brain damage.

Also another example: In my school there are some dudes playing World of Warcraft. And there are so addicted. It is the only thing they talk about. Some of them have no life at all. They never come outside, have no social life. It goes like this: Guy goes to school, plays Wow till 2 at night. wakes up, goes to school. play Wow and so on. That guy is looking real unhealthy and is even getting a bit bald!!! And this is no joke!!!
