The Fate Accelerated Edition (FAE) is a slimmed-down version of the fate-core rules designed for quick play, introducing players to the fate engine, or running high-concept campaigns. FAE characters have fewer aspects and rules exceptions, and no skills; instead, they've been replaced by six universal Approaches.
How do I get it?
Fate Accelerated Edition is available as a free PDF from the Evil Hat website for pay-what-you-want including free, on the online Fate System Reference, or as a $5 book from the Evil Hat website or your friendly local gaming store or other distributors.
