I've done the Pitt, in an unmodded game, I found it interesting if a bit difficult at the start. Haven't done point lookout yet.
I have done the Mothership Zeta DLC, which was quite funny and got me some great loot
I have now installed some mods to give myself more of a challenge and I'm glad I did.
Fallout is now a tense, terrifying experience once again, where it had lost some of it's challenge through repeated playthroughs
I highly recommend the FWE mod and the unofficial patch mentioned before in this thread. this one is also very very worthwile
