Incredible from the setting to the graphics to the story. A masterpiece!
The atmosphere is the best I've ever seen; and the story is even better. To me, "Marked One" (the protagonist, the player), is probably the most believable character compared to most games (not bone thin and not buffed out). Every detail of the game is epic.
The levels are pretty big, and with the option to be friends or foes with a faction is great.
The cutscenes that are pre-rendered look real from shading to the skin on the models. I also have read that there are 7 endings, which to me makes it one of the most replayable games.
This my favorite game, and its story and gameplay is better then Fallout 3 (better as in better in a different genre, not the same genre).
GSC Game World, to me, has shown their talent. From the story to the gameplay, this game is, as this review is classed, Revolutionary. It may have some bugs, but it is an incredible ride from beginning to end.
I can't wait to see what they have in store for us next.
