My annoyance with this is, you can pretty much run a "Blade Runner" TTRPG with <i>any</i> suitable system. You barely need to do any prep: we know there's guns, space ships, FTL, extremely good computers, etc. Thats like half the existing OOTB sci-fi settings. Pick one with the desired crunch and take a few minutes to skin it (no pun intended).
