Some of the best graphics to date and amazing gameplay make this a stellar game to look at and play.
So as I've said, Uncharted has stellar graphics. the environment is lush with vegetation and even animals, interactive environments (sorta) and mild destructible environments. The game is fairly easy in the beginning, but as you progress, you'll notice it gets harder. Uncharted almost could've gotten and M rating. You'll know what I mean once you start Chapter 18, I believe (its like reliving Silent Hill!).
While Uncharted many Pros, it also has its fair share of cons. Hand to hand combat could do a bit better (too repetitive!) and it seems as if you see the same environments over and over again.
Uncharted is a great game, period. If you want, you can download the demo first, but to me, it seems like it would just waste you time. Uncharted is a must buy.
