Personally I think Uncharted is fine with T. There's blood and such but nothing I'd really actually object to letting a 13 year old see.
Halo on the other hand is definitely too high with M, save for maybe a couple moments across the entire series.
Honestly, most games that get the M rating I'd argue don't deserve it.
I've actually played the game in question (War of the Whiskers), and there's actually a bizarre amount of violence. It's definitely more of an E10+ game, but I could actually see why the ESRB saw that game and basically decided it was too much for an E.

Oh, and one time at FYE I saw some Tom & Jerry game that was rated T. I was like wtf?
