Uncharted is an excellent game, by no means perfect but great non the less.
I'll start with the story, it reminds me of many films and games like romancing the stone and Tomb Raider but this is a good thing, you laugh at the characters and genuinely feel for them when they are in danger, the story drags to in and keeps you until the end (the twist is very good) 10/10.
The Gameplay: The Gameplay is very good. You'll spend most of your time in gun battles with pirates reminiscent of Gears of War with cover and pop and duck firing. The aiming is a little hard and the enemy take an unhuman amount of bullets before they die. The AI is execellent and they will often flank you to make sure you don't succeed. Some Platforming that you do is excellently animated and fun. 8/10
Graphics: What can I say about the graphics, the best looking i've seen absolutly gorgeous. 10/10
Overall: Uncharted is a challenge it won't lay down and let you walk through, but this makes the game much better and more rewarding. It's worth every second and definitely worth your money 9/10.
