"Conan the Exiles Sourcebook" is a 120 pages long supplement for the Modiphius D20 Conan RpG. Inspired by the on-line game, this book gives rules to roleplay it on tabletop, and stunning art from the net adorns many pages of it. As always, interesting character archetypes are given. There is a section about the Exiled Lands, but it is quite vague, so much that we'll surely prefer to have a look at the Conan Exiles wikia for more information. I don't understand why they didn't take back the rules from "Ancient Ruins and Cursed Cities".
In fact, the real interest of the book lies in its many rules taylored to roleplay survival. They explain how players can create basic facilities with their bare hands and step-by-step improve them up to cities ! For this, hexcrawl rules are given, with "resources" generation for each kind of biome, and an interesting encounter table. The survival game can be played at different scales, at the individual one, with "ingredients", or at a group level, with "material". The only regret I have here is that no measure unit is indicated for how wide those hexes are. Apart from this, there are detailed rules for (bad) weather, settlement management and war.
If you want to create a harsh setting with no stable power (no money, no national "pride") but day-to-day survival, then this book is for you !
