I would like the characters and their clothes to be able to get dirty. Grime can add depth to a character, it can show a lot social class and lifestyle.It adds atmosphere.
Also.
It would be great if there was a way to synchronise character movements together, so they could do simple dances, even folk dances, with the occasional magic spell thrown in for effect. This could be very spectacular on special celebrations or other important meetings. Dancing makes people more aware of the space they are in and their capacity to relate to it.
