I have an idea, but it's not really mechanics based. Just something for character creation. You could always take from the anime how they were made to look like their real selves, maybe make it to where we the players would have to make our characters look like ourselves. Even if we do glorify our appearances. Hey, you could even make it into a type of thing where we play our actual selves and kinda combine KHI with it. Maybe make it to where we play ourselves as we are on KHI, unless you feel that it was something that should have stayed with Shades of Blue.
Just an idea of mine after reading through this. That and my way of saying that I'd be interested in joining.
