While there are new spells and player options, where this book really shines is world building and fluff. It delves into some detail about new magic factions like gangers, political groups, militarty, cults and a few others. While I feel a lot of this content should have been included in street grimoire, it comes across more as afterthoughts that a malicious conspiracy to steal your nuyen. I would certainly reccomend picking it up, particularly if you are a GM looking for new plot hooks.
