this might just be me, but in my opinion, I think lineal spaces are less about nostalgia, and more about abandoned dread
I just don't get the same vibes from places that are just, empty at the moment, after hours vibes
it's gotta be late at night, overgrown or otherwise clearly abandoned, terrible lighting, and a constant fear that maybe someone is around the corner and pissed that you're there
tl;dr the venn diagram of urban exploring and lineal spaces is more or less a whole circle IMHO
