The dictionary definition (to paraphrase Chambers) of cyberpunk is a form of science fiction literature set in a dystopian future characterised by the relationship between humanity and technology (From cyber - and punk).

To quote Webster's (because it's easier to find online)

" The McGraw Hill edition of the Random House Webster's Collegiate Dictionary (1991) defines "cyberpunk" as "1. science fiction featuring extensive human interaction with supercomputers and a punk ambiance. 2. Slang. a computer hacker"

 Following the above, if you want a Nu-cyberpunk game, it would need to futuristic, have a punk attitude, and some technology people interact with more than they do today. The people who populate that world will follow definition 2, in that there will be those who use knowledge and skill to beat the system and hack the world to their advantage, and there'll be a big load of "script kiddies" who copy the big boys.

 In terms of modern SF gaming, I really like Transhuman Space for GURPS. While I get bored by many aspects of the GURPS engine, the sourcebooks reflect a pretty hopeful vision of the future, in which Biotechnology and artificial intelligence have gone as far as they could by 2100, and humanity's slowly spreading through space, even while civil war keeps brewing in parts of Central Africa, and there' s a huge underclass across the world. It's purposely not cyberpunk - it's not dystopian. It could be made hugely dark if you wanted to though.

Somehow, people always seem to prefer games in a troubled setting, where the conflicts are obvious, as opposed to starting in a place where everything seems happy and normal and only by digging beneath the surface can you find the trouble.

Nu-cyberpunk - it'd probably be as varied as the original was, and full of ideas that won't be taken up on.

No, you probably don't remember my character from the events I've been to.

  Interesting point...

  That sounds interesting.  You'd think it would be a theme which comes up often in larp, given the amount of non-human characters in most systems, but somehow it's an atmosphere which is hard to capture.  I think it's because it's hard to OC suspend disbelief over the idea that a person covered in latex and facepaint is something non-human, while simultaneously feeling an IC sense of disbelief that something so weird really exists.

  But somehow, I don't think I've ever really felt the boundary between the human and the inhuman to be an issue in larp.  With the character who became a vampire, the issue was not loss of humanity, but a feeling of being rejected by her god, combined with totally coincidental pre-existing phobias of blood and undead.  Similarly, I've enjoyed playing human characters who hate non-humans on principle, but it always winds up feeling like extended racism rather than anxiety over what really constitutes 'humanity', if that makes sense.  It's hatred of a different sort of person because they look funny and they're coming in here and stealing our jobs, and will probably murder us all in our beds.  The sort of deep, anxious uncertainty over where we draw the line over what it means to be human doesn't seem to come up.

  I'll bear in mind what you say about Vampire.  I'm not aware of any games running near me at the moment, and coming from a standard fantasy background I find the combat rules offputting, but I'd be interested in giving it a go.

  Noted.

  This sounds like a good idea.  How would you you actually go about doing it in practice?
