Not much time for this post, but -- here's some cyberpunk inspiration I've had lately.
You heard that Dubai is in financial trouble, right? What would happen if the companies building those crazy-ass resorts suddenly all went bankrupt -- who'd move in? What would happen? Wouldn't that be a kickin' setting for a cyberpunk game -- an extravagant metropolis on the skids, fancy hotels converted to apartment blocks full of your typical cyberpunk characters? Hmmm...
Yesterday I mentioned that thing about La Movida Madrileña, and how pop culture exploded all over Madrid after Franco blah blah blah? You'd hafta play fast and loose with your future history, but it strikes me that you could use that as a hell of another premise for your cyberpunk setting: a culture released from opression that can suddenly go crazy and do whatever the hell it wants -- and there's cyberware.
Hmm. Crap! Gotta go back to work!
