There are a lot of things good about this game. Let's get started with:

Storytelling: it is not as deep and complex as other games but it is very well developed that makes you feel interested in following the story. You have several ending, which implies several play through. I only went to one ending just for a matter of time.
Gameplay: In this area may be a little complex but once you get used to it or master it you will enjoy every feature of the game.
Length: you are always aware about the this during the game. In my case it took me 20 hours to be the game. Only 27% of total trophies were earned.
Graphics and sound: just splendid, specially the surround effect, on par with AAA shooters. Take well advantage of your HT system or special headphone.
During the game you never get bored, I like the exploration parts to get all the ruins and bones, as well to unlock safes and special places. In play play through I chose the women, If I would have time I would play it again
