I think my group had serious issues with this when I was running Burning Wheel for them. They were entrenched in the ‘Well, I have this skill, I roll it’ manner of play. When it came time in BW to state your intent…they had problems. It’s not necessarily a piece that snaps into the whole puzzle in a single, non-negotiable way.

Whenever I stopped them and asked, “But how?” play would occasionally end in a standstill. FoRKs especially caused problems for some. “How does that FoRK work?” “It just does, doesn’t it?” And I wasn’t always asking because RULES ARE RULES, but sometimes I wanted them to come up with something clever or how that particular skill/FoRK actually worked in that situation in the fiction, opposed to it just does.
