Thanks much. My only problem with doing it myself would be graphics, so I suppose I'll look around and see what threads there are on making/editing graphics specifically for this game.
I'm tempted, however, to look into province troops as a base for PD, though.
Well for something like this I don't think you'd really need new graphics.
Depends what you have in mind I suppose. I'd be fairly interested in just seeing a mod which gives the vanilla nations more thematic PD without particularly strengthening it or weakining it. So getting rid of the humanbred in EA Abysia etc. Not too hard to do.
