I think I saw a few of these fly by, but how do games that change their space to be more like the game itself fit in? This is probably a LARP-ey thing, but also, say, futuristic online games doing things with multiple text channels to be more internet-ey, or other stricter communication rules that mirror what’s going on in your fiction.

Also, I’m down for players having second person narration rights in places. I can think of some powerful uses – Characters like Exalted or Nobilis nobles who have a lot of authority over an NPC dictating their experience could be really moving.
