Fallout 3: The Pitt Review (Dehds)
This is by far the shortest DLC (I spent half the time - 2 hours - collecting ingots :D). While the rest of the DLCs provide some change of scenery, so does this one but in the opposite way. The area is a lot more ravaged by conflicts and radiation and it a much more depressing version of the Wastelands. The story is in a similar way like the Wastelands, as in you get to make a choice, but again it's been more intensified as the choices aren't clearly divided by good and bad, so requires you to make a tougher call, which I quite enjoyed. My inner loot goblin was quite happy with the collectables because they were confined to a specific area and there was 100 of them, so you can just completely immerse in finding them, without having to worry about keeping an eye out for the whole DLC or having to wait to make progress.
