It's not that I don't like Numenera, but I have yet to give the system a fair shake. But this thread is not about the system.

I own the core rulebook and it's beautiful and the setting parts are... I don't know, hit and miss? There are maybe half a dozen intriguing adventure seeds there, but I expected a bit more weirdness. The bestiary is great, though.

I'm always in the market for weird places, situations and monsters I can spring on the PCs, be it in Numenera, or D&D, or Traveller.

I've been eyeing the Into The Ninth World Kickstarter because books about the ocean, and outer space, and other dimensions, are bound to have the sort of things I can use.

But there are already quite a few Numenera supplements out there. I'd like to know whether anyone here's read any of them, and what do you think of the book(s). Are any of those worth picking up just for the fluff? I'm mostly thinking of the Guidebook and Bestiary, but if any other book's packed with good ideas I'll get it.

Get the Numenera Bestiary. It's absolutely beautiful- amazingly good art, and some wonderfully bizarre critters. Even if you're not playing Numenera, you can easily port the creatures over to other systems, especially cross-genre ones like Rifts or CthulluTech.

The tech guide is just a magic item book but it does have the AI character rules. Honestly, the Ninth World Guidebook is wonderful and fleshes out the world more. Giving you nearly 3X the amount of stuff to explore.

I find the Character Options minibook great.

Both the Numenera Bestiary and the fully compatible The Strange Bestiary would be my top picks, followed by The Ninth World Guide. All three are fluff heavy. The Technology Guide and Character Options are more crunch oriented, although Character Options does also include regional descriptors which mix the fluff and crunch.

bestiary and ninth world guide are must haves, the rest are good but i'd probably leave it upto you to decide how useful since it'd be your game world
