I don’t care for it. It does some interesting things, in base building. But having played it a lot mostly because my friend group likes it, it’s very janky. It does not feel close to 1.0. And, while there’s some fun to be had, everything outside the horde nights just feels like busywork in a way I didn’t feel with Valheim or Grounded.
Short answer: read Jack Vance’s ‘tales of a dying earth’. It’s the reason dnd magic is called ‘vancian’.
Longer answer: in that series, magic works by just remembering words, and then saying them. But these magic words are powerful things, weighty in the mind, hard to carry. And, when said, they tear themselves out of your mind, causing you to forget them.
So, not ‘spell slots’ per se, but the idea is you’re prepping spells almost as a ‘potion’, something you carry in your mind, and consume to cast out a spell.
I mean, that’s the point of Dune? The ‘prophesies’ aren’t real, they’re seeded by the Bene Gesserit, the same group that spent millennia breeding the ‘savior’. And, he’s not meant to really be a savior, but their catspaw.
But also, he’s definitely not actually a savior, on account of all the death he brings. It’s complicated, but overall a deconstruction of white savior narratives and similar stories.
