An updated version of the Beyond Cyberpunk hypercard stack from the early 1990's. It's kind of dated (cyberpunk's kind of dated, truth be told), but as a historical resource, or a resource for fiction writers you might find it of interest.
A realtime strategy game in which you compete in a virtual space with others to build the biggest, most robust network you can while attempting to compromise or crash the networks of rival system admins. It sounds a little like Starcraft meets Neuromancer with a healthy dose of the movie Hackers thrown in for fun. Runs on Windows as well as Linux.
