Games should be like Uncharted 2. There's little wrong with it. Game play is fantastic as so the story.
The first problem you would see in Uncharted it is that the campaign is only 8 to 10 hours, and that's when you play it for the first time.
But the campaign is so good that you wont play it just once. You will play it to complete all difficult levels and after that you'll play it for fun.
The game play works very well, even if you don't play many videogames the game helps you. It really has the feeling that you'll never get stuck, and you'll never do because the flow of the game is conceived for that. Some say it's a bad thing I don't think so.
Some puzzles could be more difficult, but that's just it.
The story I do think is the most brilliant factoring in the game, well done, brilliant voice actors and it integrates so well in what the game is.
It doesn't feel that you're playing just to finish the game but to complete some legendary quest and that's the feeling Uncharted passes so well to the ones who had the pleasure to play it.
