Fallout 1/2 are excellent games even by objective modern standards.

While the UI is a bit archaic by modern standards, it gets the job done. Late 90s UI/UX was noticeable better than what RPG games offered in the early and mid 90s.

Some elements of the gameplay are also subpar in hindsight. I find I have to cheese a lot of the early game combat encounters and get in pretty tedious kiting sessions (and even save scumming).

I bought Fallout 3 on release, but I bounced off it after a few hours of play. I've been meaning to replay it, but just haven't gotten to it. New Vegas (technical glitches and limitations aside) is a whole different story though.
