Eh, it's not for everyone.
Even for it's time, Fallout 1 was pretty niche, all things considered. Not everyone's going to like it, and there are some things that, were it done today, would likely have been improved upon a tad.
Some games I can go back and play over and over again. The 2005 remake of Sid Meier's PIrates! has been faithfully installed on my computer since it came out (and I've probably got the - now surely demagnetized - boot disk of the original game lying around somewhere,) as I'll keep coming back to that. Deus Ex I just can't hack, though.
When Fallout 1 came out, that was like a game custom-built to my tastes. When Interplay imagined the target audience for that game, they saw my face. So yeah, I'm nostalgic. But I still love playing that game, and revisit it from time to time. Doesn't blind me to that game's shortcomings, but I like a lot of what they did with that game. I still stand by the conclusion that thus far no role-playing game has surpassed the cutscenes at the end of the game, and the manner in which your past actions altered the epilogue.
But yeah. If you don't like the game, you don't like the game. There's a lot of games out there. I'm sure that's not the only one we'd disagree on.
