I've noticed that many players have requested for a turn order option or some way to control how players participate, because not all players have the same availability to play on Storium.

Some enthusiastic players end up aggressively posting, while those without the time... come back to find that they can't properly respond to other players who've attempted to interact with their character.

I thought, perhaps, a "reply" function in scenes would allow casual players the option to engage in the collaborative process at any point in a scene (and not feel left out). They can't play cards in this "reply", but at least fill in the gaps where their character should have been responsive to other characters.

Of course, it would be up to the players / narrator to be respectful of this function, so as not to step on the toes of players who have already written moves that take place chronologically after this reply.

By not allowing cards to be played in these replies... it might be a way to allow players to still flesh out character interaction and develop the story asynchronously without disturbing the gameplay mechanics.
