I know the author says the Faerun stuff isn't compatible with other mods... but.... :D

I started up the game, and for giggles, I loaded up the Giant Earth Map mod, as well.
Also the In Game Editor.

So... game loads, I go to the In Game Editor, and glance at the map.
It definitely is the Giant Earth Map.
So... move my settler and units over to Ireland.
Start up there.
I'm now building up to upgrade units to Dragon types, and invade the French Gnomes with Irish Dragons.
:D :D :D

The overlay puts all kinds of Faerun land and sea tiles on Earth continents.
Fanfreakintastic.

10/10
Would invade Gnomish France again.
And again.
And again.
