basically what @AmLash said
I might add … it is a great system to make up your own monsters on the fly
superfast und super easy
I ran the “Iron Gods” PF Adventure Path for my rpg-group using the Numenéra rules,
and turned the weirdness of the setting up to 11
suggestions for dm-ing:
- as a dm craft the cyphers/artefacts/oddities, that your players would be able to find before, so that they will fit the current theme
(e.g. if your party explore an old transdimensional-biomancer ship, let them find transdimensional biomancy ship stuff) - allow your players to get creative, especially when using cyphers/artefacts/oddities, while still keeping the weird-flavour strong
(e.g. allow them to combine two cyphers into a new stronger one, but add a weird side effect with a severity depending on the crafting difficulty)
have fun
