I started playing the less-violent 'T' games by the time I was 10-ish and I owned my first 'M' game at 14. Of course I'll keep track of the content of the games, but I don't think those guidelines are unfair; There are plenty of good 'T' games.
But honestly, I'll probably play video games my whole life and I don't think I'll ever run into a problem where I'm unsure if a game is suitable.
