I finally got around to playing Point lookout this weekend, and I would just like to say I loved it. To me, it was easily the best of all the DLC's available for Fallout 3. As a somewhat intelligent person living in the Deep South, I can not express how gratifiying it was to get to shoot a bunch of inbred rednecks in the head with an assault rifle. The only thing that would have made it better was if they were wearing some "Roll Tide" T-Shirts or something.
And so, from the bottom of my heart, I want to say thank you to the entire Fallout 3 design team. Point Lookout was easily the best $10 I have spent in a long, long time.
