Query: Part of the Core to the System

There are three books that are "must haves" in the SR world, and this is one of them, with the other two being the main rule-book and Rigger2.Sure, you can run a campaign with just the BBB (Big Black Book, aka main rulebook) but why? Add in the spice of the decker, give him a place in the group. Combine this with the Rigger book and you have a well matched system. GMs! Give your deckers a reason to exist, buy this book and scare them out of the matrix!
