My Fallout career also started with Fallout 3, but since August last year, I've had countless Fo1 and 2 playthroughs, and I'm now proud to say I'm a Veteran! ...In the making maybe :rolleyes:
I've suggested already in the DLC thread how a DLC/Expansion intertwined with the Core region would be a great idea, but we'll see after Dead Money.
I now feel obliged to direct you to the DLC thread too:

Feel free to add any of your ideas there!
