Great Story, great multiplayer, worth the buy and time.
The story was also pretty good, although sometimes the dialogue just felt.. a little repetitive. Nate's witty talk was funny at first, but at some point in the game, you'll be able to predict some of the dialogue. Nonetheless, great story overall, no plot-holes that I have come across.
The graphics were simply amazing. The environmental design and landscape was great and realistic. Explosions, train wrecks, snow mountains, you'll come across many places that will most likely fascinate you.
Overall, if you're a fan of Uncharted, you'll love this game. If you're a gamer looking for something new to try, Uncharted is a great choice and worth the buy.
