Ran a one-shot of #Numenera today. It was fun, but I always find the deep lore of the setting a little tough.
I understand it's not necessary to use the lore, and I can set my game in a wholly unexplored region of the Ninth World, but I still find its presence in the book a bit weighty.
I think I prefer the looser world building of something like Vaults of Vaarn, a somewhat less detailed science fantasy world. There's quite a bit less detail, more a mood than an atlas.
I've considered just using Numenera/Cypher rules in a #VaultsOfVaarn setting.
