Converting Cyberpunk stuff over to Shadowrun:
Why not stick with what's easy, convert one-for-one. That's what you wanted to hear, right?
Everything converts real easy when you use one-for-one ratio. Beware of skinweave. Do not let them comparison shop between the Cyberpunk book and Shadowrun. All of Cyberpunk stuff should be considered high tech, requiring that "edge" that allows a character to get that kind of stuff. And yes, full borgs are fun. Full borgs on cybermancy sounds too good to pass up. Maybe I'll start doing this again.
Be warned this is worse then letting your players read Cybertechnology, or have free access to Shadowtech. Some of the stuff in CP2020 just does not work in Shadowrun. You have been warned.
