Seeing a gif in my stream was nice, I knew it meant an IGRC post.

I’ve been thinking that structure and characterisation are deeply embedded inside each other. So a players ability to define themselves, proactively or reactively, is quite dependent on what the system and GM throws at them.

Burning wheel supports proactive play so well because the GM is told to facilitate it. Perhaps D&D promotes proactive play only by bent of it having so little to say about the narrative in its mechanics.
