Previously someone asked about the resources to follow along the rules with CoS. Nebula Jazz is using Fate Accelerated. You can get the book and PDF for $5 or just the PDF for pay what you want including $0 but you should flip them a few bucks. I picked up the PDF to read through as I don't have much familiarity with Fate. I'll probably grab the book next time I hit my FLGS.

Fate Accelerated PDF (DriveThruRPG)
@AdamKoebel Are there any other Evil Hat resources you use, do you reference Fate Core at all?
