I'm pretty sure that if I wanted to play the other games, I would have by now. I mean, FO3 is sitting in the drawer with the xbox games, and 1&2 are on the shelf behind me~
I'll stick to NV and just reading about things that have happened already.
i grew up on FO1 and 2, i can't play them anymore cuse they are just not game play apealing to me anymore, but a least tray FO3 it will give some more perspective on the general on FO
