Very well realized world, setting and the story was very enjoyable. There are some outstanding quests, but the majority of them just don't stand out and feel like filler, making the game drag for longer than it should. 

My major problem with it is that it's unfortunately trapped with Fallout 3 mechanics, which are just dreadful. It's not fun to navigate through the world, the combat is pretty terrible. Even though I was very interested in the conclusion of the story, these two points made the experience very frustrating by the end.
