Personally, the book Hardwired and movie Logan’s Run had the biggest effect on me. eXistenZ came close as well, and Neuromancer and it’s sequels are classics. As far as ttrpgs, Shadowrun and Cyberpunk have unique things to offer, but I continually find myself drawn to the “stranger in a strange land” trope perpetuated by the show Futurama and tabletop games like Metamorphosis Alpha and Journey to the Barrier Peaks.
