Virtual law is interesting because these environments are in one sense fictional, in another very real. People invest real money and time and create real relationships.

We need to give careful consideration to how copyright operates in virtual worlds, where everything is mediated by the software. To a certain degree, copyright law is the umbrella regime for virtual worlds.
