I'm a regular gamer myself and also a Dad of two teenagers, who like most others spend their evenings, weekends and school holidays glued to their games consoles.
Having looked through your website and heard the sad story which started this campaign - I have to say it's a real eye opener!
I immediately went up to my kids' rooms and told them about it and also put some ground rules in place to regulate their gameplay.
Surely the games companies can see that by a few simple measures they could help to prevent further tragedies occuring.
I'll check back regularly to see how your campaign is progressing - Good Luck
