Fantastic, Johnstone Metzger, thank you for the input.
I think, going through both your book and DW, the DW supplement-ness of SWvM jumped more out at me. Like, in terms of underlying themes (action/adventure!) as well as in where they diverge (ambition and ideology rather than cash-money as motivation).
There are also super-interesting implications if you carry Dungeon World to its logical scifi conclusions, like the fact there’s a Black Gates of Death at all, and one assumes demons and deities (if a Space Cardinal is in play) and so on and so on.
Looks like I’m gonna pick up Dungeon Planet as well, yikes.
