Glitches

The R. Talsorian sourcebook for Cyberpunk based on Walter Jon Williams' book Hardwired (1986) included some interesting variations on the core rules. Most significantly, the netrunning rules were revamped to a more realistic system. CP2020 is a good game, but the treatment of cyberspace is very idiosyncratic, to say the least. Another thing I like is the table of "glitches" for NPCs. These are personality quirks that can give characters a distinctive personality. It's like a quick-and-dirty Life Path. To determine the number of glitches, roll 1D10. 1-5 = 1 glitch, 6-8 = 2 glitches, 9-10 = 3 glitches. Roll 2D10 for each glitch and cross-index on the Glitch Table.
