Battle for Wesnoth is set up this way.  I don't know what the code does, but 
you can go wild creating new classes of character by mixing up new 
combinations of attribute settings in new configuration files, and injecting 
them into the standard game config files.

AFAIK you are stuck with the attributes the game is programmed for.  I've 
seen no way to create a new dimension for the game -- Conversation, for 
instance, with currently unknown attributes like vocabulary or tone.
