I am I addicted to video gaming?

I'm 13. I go on games mostly everyday (sometimes I miss a day) for 1-2 hours. I go on games that are over my age limit like COD, battlefield, brink, oblivion etc. I also go on racing games abut like burnout paradise and gran turismo 5 etc. I have good friends who like me and I get good effort grades and marks and stuff at school. Most of my pocket money goes towards games and consoles and stuff. I occasionally go to friend's houses But they don't come to my house alot but that is mainly due to not getting round to ringing them up (because I forget/my mum forgets and not because of gaming) And shyness. I get a little bit excited when big new releases are coming out but not to the point where I go to a shop to buy first thing in the morning and where I go and miss school because I got a new game. I never bunk off school for gaming but when I Am off school sick I sometimes go on games. Me and my friends chat occasionally about games. Am I addicted And is it ok to go on violent games thAt are 16/18's?
