Hah! I knew I had seen a discussion about the need for mod nation guides back when the world was young. Erm... in 2007 I mean. Thanks to the resident necromancers for digging it up for me.
To get the thread back on topic: I've written a quite extensive guide on Arga Dis here:
http://forum.shrapnelgames.com/showthread.php?t=38517, for those who haven't come across it yet. Unfortunately, it's not of a size to allow copy/pasting it into this thread, as the shorter playing guides in the beginning of the thread, but links work almost just as well, right?
