This is a tough one for me.

I already have the 2018 edition of the Sourcebook. This new edition has - apart from the utterly glorious cover art - an updated layout, updated visuals for dynastic genealogies, and updated maps of the Underworld and previous ages.

If you haven’t got the Sourcebook, and want to understand Glorantha, then this is a must-have purchase. But if, like me, you have the previous edition then this is a purely luxury purchase. And with the Lunar cults book coming out sometime in the next couple of months, and so much great content on the Jonstown Compendium it’s hard to justify the price for those updates. I make no promises though.
