I’ve been looking at a lot of gmless one-pagers, and I can see different sorts :
games where you set character projects and frame scenes to confront them.
There’s more improv in them. I think that comes from the “american freeform” movement ?
games where a mini-game serves both as a relaxation from creative effort and as a resolution mechanic, with narrative elements going in and out, mixed or altered. Simple narrative processors, like a over/under roll, or more complex, like a pbta Move.
games with an oracle, the heart of most solo games.
I don’t mean to be exhaustive, divisive or anything. I just would like to follow up on this observation : which theories touch upon these differences and how ?
