From the very beginning of the game you will notice that the graphics are absolutely amazing. It's amped up even further by the incredible amount of detail in the world. It's not enough that the textures and draw distance, from a technical perspective, are great but also that little details fill the world above and beyond what we have come to expect from video games. I've heard some people talk about how the environment and world can be considered a character onto itself and if this is the case, the environment in The Last of Us deserves a 10 out of 10.
If you have a PlayStation 3 there is no reason why you shouldn't buy this game (unless you are not old enough of course). The story is incredible, the gameplay is fun, and the graphics and sound are amazing. Naughty Dog had a lot to live up to with the release, but they have delivered in spades. I just hope we don't have to wait too long for a sequel. This game is everything you were hoping for, and more. Go get it!
