I'm a West Coast Eagles fan and our captain of several years was taking drugs on a weekly/bi-weekly basis, wound up winning the Brownlow (Aussie Rules season MVP) and we played in two Grand Finals for one Premiership. I loved watching him play and yet I don't take drugs nor am I interested in them. I will play GTA5 and I will still not take drugs.
I agree that our classifications don't appropriately resemble society, their education level or their access to paraphernalia about drugs, sex and violence as well as drugs, sex and violence themselves. When GTA5 comes out I WILL drive down the footpath running people in Vinewood. I WILL walk into gang territory and open fire. I WILL walk along the beach punching random people before defending myself from attack, with gunfire if I have to. I will not be doing these things in real life. I agree that many games are not for an under 18 audience and there should be measures in place to restrict the access to children but let the rest of us, who know the difference between life and fantasy, play the games we want to play as they were intended to be played.
Thanks for reading, I'll be in my meth lab if you need me.
