Whilst randomly reading through the MTW Modifcation forums, I stumbled the intro to modding thread. In this thread, three types of mods are outlined and defined, including the campaign mod;

Campaign mod
A campaign mod only adds a campaign, similar to the Early, High, Late campaigns. This is the only kind of mod that does not interfere with the installation at all. You can have thousands of these mods as long as they don't have the same filename.
These mods focus on changing small strategic things such as starting treasury/units/buildings/provinces.
"That sounds good", I said to myself, and used the search utility for 'MTW Campaign Mod', yet I was suprised when I found no results that seemed to be what I was looking for. So my question is this, unless I've misunderstood the definition/function/purpose of campaign mods, why can't I find any?

Any help would be greatly appreciated.
