>>32531672>should the tone always be kept light? how much serious / "dark" content is acceptable in a pretend anime character's lore?It doesn't have to be. But unless you are very dedicated to your rp your streams will most likely end up having a light tone anyway and I think that's fine.
>is there room to add depth such as through themes, morals, or deconstruction, or should it just focus on being funny / cool / generally entertaining?Those are all great if done properly but I think most people would probably enjoy funny / comedic lore the most. There is a reason why one piece and one punch man became so big.
>should the story be structured ahead of time, and if so how far ahead? how much influence should stream moments / audience in-jokes have on the development?You should build your lore with your streams. Think of it as a GM who has a basic plotline planned but will adapt it if need be.
>anything else you consider importantCreating fun or immersive moments with it on stream or in any other medium would be the ideal outcome imo.
