How would the ESRB rate your game collection?

I'm very open to all sorts of games, be it genre or game rating. That being said, I've noticed that, more often than not, I'm buying mostly M-rated games. It's not a huge surprise to me. If given the option, I'd rather shoot someone in a game than shake their hand. It is a bit unique to a portable system though, and while I don't only love the PSP because I can play M rated games on it, I do appreciate it. Are you similar to me in this regard? If the ESRB were to give a blanket rating to your PSP game collection, what would it be? Did you get the PSP partly because of the ability to play more M rated games?
