Finally finished the main story of Fallout 3.
I had played it before, but stopped halfway through.
I feel like I still haven't seen 75% of the map though.
The main storyline should have taken you to more places from where you start sidequests, during which you discover new places, and so on.
Now you have to just wander around the wasteland until you find something good.
There's also not much of a climax or buildup to the story. I didn't expect it to end so suddenly.
To be fair though, I absolutely love the game mechanics of this game and although I would have liked the story to be a little more exciting I really enjoyed it.
