Should i let my son get this game?

If your son has played Fallout 3, Grand Theft Auto, Halo, Gears of War, in's Creed, or similar games then he will be fine with Uncharted. It is not a violence focused game (but it is an action focused game). It is actually heavy on character story which your son may enjoy as it is like playing a action movie. Maybe look at some reviews on the internet to make your final decision. Also look at the ESRB rating on the back of the box if you are still not sure. Unfortunately I cannot remember the name but there is a website that is specifically designed to help parents find out if a game is appropriate or not. Hopefully someone else will post it. Also to some misunderstanding someone has posted that Uncharted 2 is not online but actually does include co-op and versus multiplayer. Hope this helps
