One thing which I'd find interesting if GM'ing a game would be to allow the players some ways to f.e. enhance their own troops. I'm pretty sure you can change some things in a mod after the game has started, like turning a weak unit into an average one or altering recruitment costs or the like.
The problem with this is that costs must be in the mod used by the players. Stats would be nice too, but are probably not as necessary. Still, it could cause problems if the game was hosted on llamaserver for instance, as it may not be easy to alter the files remotely. I also believe dom may have to be restarted in order to reload the mod, but I'm not certain.
