We have a linen closet that for a time in my childhood was emptied out and made to serve as the "Nintendo room", containing an NES hooked up to an old Commodore 64 monitor. I still associate that fabric/crafty smell with 8-bit gaming.
I went on a road trip through the mountains in central Colorado during the summer ~7ish years ago. I still don't know what the smell actually was but every once in a while we would drive through certain parts of the mountains that had slightly sweet and clean/crisp smelling air. Never forgotten it.
The closest I can think to describe it would be something floral like freesia+ a woodsy Sequoia/evergreen combination.
