I never was a fan of this genre but there was one I bought on the used shelf of blockbuster for $5.
Tenka or I think it was fully called: Code Name: Tenka
I don't think anyone knows about this game. It actually had a story, a reason for him to do the things he was doing, some puzzles to figure out (but honestly nothing hard, just "go there, activate this, go back to the previous room, click - done" type of ordeal, and not all boards had those, maybe four.
It had a gritty "slum and dirt" type feel to it, in a universe that was future but worn down (sort of reminded me of the 'Aliens' world) - too bad you never got to see most of it -just the interior of buildings and a few dark streets (dark because of draw distance) but I did feel the black gave me the feeling that things weren't working right or that technology was 'run down' despite being, what we would consider, future tech.
It's not going to win any awards by today's standards but I do think it's worth it to play.
edit:
doing a quick search on amazon found it:

edit 2:
I honestly think the music is also a unique thing about this game - really sets the mood and, at least to me, never got boring.
