Usually when a game is advertised as asynchronous, it's generally reassuring you that it's an atmosphere where you don't have to worry about the game moving on without you. However, that isn't the case with Storium's system as is.

Some enthusiastic players end up posting a lot, while those with less time online... come back to find that they can't properly respond to other players who've attempted to interact with their character (many posts earlier).

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). Essentially, a player can write a reply to a past move, if they feel the need to flesh something out or 'reply' to another character. Cards cannot be played in this "reply", but at least, players will have the opportunity fill in the gaps where their character should have been active. No feeling of being left out.

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.

I thought 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.

I thought it'd be a fun way to deepen the story-telling from a more non-traditional angle. It'd be cool to open up and read off-shooting threads of replies to past moves (if you feel like taking a trip down the rabbit hole).
