I've still got my stuff and up until last year, I was on-off running a CP2020 campaign.
I did run a campaign for 7 years in the 90s (1993-2000) - only managed to have one character kill himself through stupidity. The rest got "upgraded" piece by piece. :D
Preferred 2020 to Shadowrun, but when there was a dearth of CP material in the late 80s, and SR snuck a few books in while no-one was looking, I grabbed them and converted them - removing obviously magical/fantasy stuff and substituting the mundane versions.
The ex-president of a games club I used to belong to wrote the first Rigger black book (Phil McGregor - who also wrote stuff for other rpgs back then).
A friend also wrote the Australian bit for the PacRim sourcebook (not well received here, but those people tended to take it too literally - and not take-the-piss-alternate-future-that-wasn't that it was intended as.).
Hey! Where'd ... Everybody ... go?
