U3 These control the parameters of the new technologies. For this example, I'll create Nanotechnology, Cybernetics, and War College. Tech A, and type your new technology's name as shown. U2 Next, decide on how important you want to make your technology to the AI, and if it will be more attractive to warlike or peaceful civilizations.

Negative modifiers have the exact opposite effect.
U3 Next, decide on what you think are appropriate as required technologies to research you new technology. For example, Nanotechnology would require Miniaturization and the Superconductor. Go through the chart and find the three letter code for the two prerequisites and enter those codes as shown. The era of a technology is the first number. The type of technology should reflect what it does.
