yes the mod is
Eras Total Conquest
it is accurate as in there is way more water than land
since the map can only be so big accuracy needs to be sacrificed for game play
so there needs to be way more land than water
you can create a rome total war mod with a world map
the scale will be smaller than the m2tw one but it should work
the problem now is making a great mod with very few regions
199 land tiles is not much for the entire world
but its not impossible
one idea I thought about would be to use forts in the less important areas
like small islands
the first step to get this rolling would be to create the map
well that's what I would do
so that anyone who might be interested in helping could install this new map to see if it would be worth their time to help improve it
