Has this been mentioned here? A Kickstarter for “creature cards” that have monster art on one side and the stats on the other. They do have a set for Dungeon World, and that seems like something that’d be really useful.

I don’t know about really useful. I keep hemming and hawing on backing it. They could be a fun alternative to page flipping. And I like the idea of making the players draw their own doom.
