Thanks for this cool mod!
Partly as a player a HUGE map takes a HUGE amount of time and it would be nice to have another option - Standard size (8 players) for the battle of 7 kingdoms?

As a fan too, however, GRRM has been vague about the size but certainly Westeros is nowhere near huge, maybe great britain sized (or bigger with all the North), but anything bigger than standard gets a bit nuts.

I mean, it's crazy that I have like 20 cities across the reach some of them massive and there's still unoccupied land I don't even need to fight for around some of the edges.
It's even crazier there's like 20 cities in the North when in the books it sustains only one major town (White's Harbor). The North is big (according to King Robert "almost as large as the rest combined") so if you don't make much of it tundra (and almost none of it grassland) the play is just too weird.

A standard sized map generally poorer in resources would really let the seven kingdoms get down to business!! And that's the point since no one's flying to Alpha Centauri :)

Finally if you wanted I think adapting the ancient wonders (Great Pyramid of Mereen, the Gt.Library of Oldtown, the Colossus at Braavos etc) would be pretty easy and add back in a fun dimension.
