Now this is a thread that’s caught my interest! Some of these concepts I use regularly in certain roleplays or are concepts I’ve enjoyed using in the past, especially asymmetric information, when players all have secrets from each other that they aren’t supposed to share until it comes out in rp. 

One concept I really miss from my days in more free-form roleplay was a group timeline, where certain arcs and events happened, and if things slowed down, the group would just skip ahead and we’d workshop what had happened in that arc to get the characters where they needed to be in the next section of the timeline.
