I know I'm going to get flamed for saying this by the old school fans, but I would also give Fallout Tactics a try if your planning on playing the first two as well.
I know Tactics doesn't get much praise from the Fallout followers, but I was never much of a gamer until I joined the service and needed a diversion on weekends not spent deployed or in the field (Jacksonville, NC did not in my opinion offer much of a night life, unless you plan on giving away numerous one dollar bills). Anyway one of the first games I picked up for new sanity inspiring PC was Fallout Tactics. I loved it and it turned me on to both Fallout 1 and 2.
Maybe that's why I enjoyed it so much as I played it before the other two, but for those that love knocking it I found it the perfect gateway drug to the Fallout universe and it helped garner one more devouted Fallout fan.
Just saying you might want to give it a try as well.
-Cheers
