Blood is great. Blood is good. And, I like seeing it on other characters' clothing.
But, this could extend to other things, such as sewage, toxic waste, dirt, dust, random giant arachnid ichor, soot, garbage, vomit, shit, etc. We could have a whole rainbow of dirty gear messages, depending on what we've gotten onto ourselves, or gotten ourselves into.
So that brings me to another suggestion:
Laundromats. Come on, if we're going to get dirty, there should be separate places to clean laundry and to clean ourselves. We shouldn't just jump into the shower every time our clothes started stinking or getting dirty. Hrm. Speaking of showers, there should be a communal shower at the coffins on Red and Gold, and more people should actually be able to automatically notice when a character crosses that threshold where raunchiness becomes an obvious hygiene problem.
Just thoughts I'd like to share, even if they would make the game more complicated if they were introduced.
