Haven't GM'd Cyberspace in decades.
This was ~22yrs ago and we almost never used the Net part of the game. Full immersion would take way too much processing power, imho.
I'm amazed at my lack of originality, but the main influence was Bladerunner and Mad Max. Add a bit of the movie Wired (it had some good small robot ideas) and Robocop, Max Headroom. A megacorp used some terminator robots and I was working on mech ideas. Always wanted to convert ED209 and Elemental Armor from Mechwarrior.
Converting from Cyberpunk 2020 to Cyberspace would be easy enough. One had a d10 base and the other d%.
Cyberpunk 2020 did have cool gangs. (Bozo Clown Gang! Had one player in the gang who replace a lung with c-4 on a dead man switch. Crazy..) but Cyberspace did have some cool professional military outfits. I guess we'd call those training packages, today. Also liked the Socio Economic Class ideas for Cyberspace. (Cyberpunk had a ton of supplements that weren't heavy in page count but info dense.)
I do like claud1961's China ideas. Sort of like a version of Twilight 2000 on home soil.
There was a brief mention of limited space travel and Mars colony unrest. Always thought that should have been explored more. Cyberpunk 2020 had a few good resources for NEO that would convert easily enough.
More recently, Kim Stanley Robinsons Mars series is an idea I'd like to explore. IIRC, there was a Mars colony that had one or two lines of description in Cyberspace. Near future teraforming was described for Venus in the Cyberspace rules. Robinson's Red/Blue/Green Mars series had some game tech elements.
It might be had to find but Underground had a cool Cyberspace/Paranoia feel. All tech was bio based though with a troops coming home from Nam to a thankless society theme.
I wonder if my current group would like to dust off the books..
