Would it be wise to buy the first two before buying this one?
		
		
	 
 
You wouldn't necessarily have to.You would just have more familiarity with the storyline, characters, and so on but I wouldn't think it would be a must. I think the game would support itself with it's gameplay without having any background into the first two. 
 I think you can buy a combo pack with Uncharted I & II for only 39.99? If you don't like it you save 20$ and if you do you get 2 great games and countless hours getting retinal burns from your TV before you tackle the 3rd game.
