The veritable deluge of DLC coming from the Bethesda's sky of Fallout 3 is unprecedented and commendable, hopefully its a good sign of things to come from other developers. They kept me coming back for more every month and a half to a game from Christmas 08, happily handing over my dough for a small sliver of their sweet sweet pie. On the whole though the DLC I found to be somewhat disapointing, Operation Anchorage was a nice experiment but lacked any of what I found interesting about Fallout in the first place, and the Pitt was mercifullly short as it was pretty much terrible. Broken one me over for the simple fact that it increased the level cap (I had been floating on 20 for a long long time) but it was a tad boring and there was a fair amount of recycling going on. 
 
And then Point Lookout comes along, and I feel that this is where Bethesda got it right. Fallout 3's sidequests I found to be far more interesting for the most part than the main quest line, there was something special about wandering toward an undiscovered location and uncovering whole sub plots, characters and truly unique situations from the rest of the game. I relished the discovery and that happened for me time and time again (that what I loved about Oblivion too). With Point Lookout Bethesda just gave me a large new locale and some truly excellent side quests, It still felt like Fallout whilst still being different enough to make it feel new and fresh. Theres a bit of classic horror, some wacky cults, the nautical element of the coast, and the crazy deep south hillbilly vibe, not to mention great characters like Desmond, that goul was a total dude.
 
In short its what I wanted from Fallout DLC from the get go, just more Fallout, was that so hard Bethesda? having said that I still enjoyed Broken Steel and Mothership Zeta was atleast better than the first two packs.
