Actually, I love large maps to (I played Large Faerun 'till I drop
). Don't worry about size of those maps. Like Boron said, they are well worth the download and lots of people have fast enough connection not to care.
Personally, I'd love if you could make some 1000 provinces big map with Faerun thematics for Dominions 3.
I'd wait 'till Dominions 3 is out before populating it with independents, nations and sites as noone knows what will be new (500 more units alone is a lot) and it would be a shame not to include it in such map (asuming you actually make something THAT big.
I know I'd play it.
I know Gandalf would play it too.
