I just had trouble getting into my vast undead roman legions being led by somebody with a babylonian name. This mod is extremely trivial; it has no effect on game balance at all. I wouldn't mind increasing the length or rules of the pythian name lists, but I'm not sure if that is possible. I also couldn't find any documentation or examples of how the custom nametypes are supposed to be used. I'd be quite likely to use some documentation on those commands to make some sort of improvement to this mod.
