I was... nine or so? Max Payne, Halo, Splinter Cell and all that stuff. I had a PS2 as well, but I don't think that we ever had any really violent games on that.
Anyway, I'm perfectly well adjusted - though probably slightly biased in my opinion on that matter - doing well in school and so on. I haven't become a satanist, I don't rape innocent maidens, take part in mass murders or anything of the sort. Take that, fox news!
