As a player, I like having choices between what type of character to experience the story as. And while there are probably plugins that could do this easier, I enjoy finding ways to do things with events instead of cluttering up my project with yet another plugin when the opportunity comes up.
In short, this works as a blank map with three walkable tiles that update the picture when the character steps on each tile, all surrounded by events that lock in the current selection when activated.
I have used this for Character Selection, class selection for a single character, and have looked at it as a way to give players a nice interface and informed decision making for a possible skill upgrade system I am working on.
