What two or three existing MOD nations are good for reference when creating a new nation?
Thus, if I have trouble with some modding commands I could compare my modding information against a good working one.
Yeah I think just about any mod nation is worth a look. People organise their code in different ways and some mods make use of commands that others don't, of course.
The example mod made by qm is in the dom3 directory as per standard. It's a bit old, but it has more comments than most, so might be useful.
