I didn't see a thread about this, but would really like to discuss this, and so, ta-da, here goes.
The last of us is a survival (horror even?) game that takes place 20 years after an infection has spread around the world. This infection causes people to lose themselves and become carriers, their only purpose is to kill and spread the decease. Joel, the main hero, is traveling the destroyed and chaos-filled world together with a 14-year old girl, Ellie. Together, they must stay alive and hide from the military, survivaors out in the wasteland and the infected. With limited supplies and ammo, the game keeps the challenge up at all times.
Very important note: There appears to be a bug in the auto-save system of the game. More about it here: http://www.thesixthaxis.com/2013/06/14/the-last-of-us-has-a-nasty-autosave-bug/
The game will stop saving, and will prevent you from manually saving. To work around this bug, you need to constantly check your menu. If you see the auto-save has stuck, you should quit in the method mentioned in the article. Here's a quote for anyone who can't access it:
Don't do as I did: Play the game for 5 hours straight, and then read about this bug. I'm terrified what will happen if I shut down the PS3 now!
