Map filters

we can add additional map filters such as

"real maps"
(France, mediterranean, japan and korea, USA, Central America, Brazil, SOuth America, Middle East, VOlga/Don, Easter RUssia, Falkland islands, NZ map, Australia and polynesia map, and Japan, Navajo map, Iberia, GB map, Boston/NY, italy etc...)

"historical maps"
(Rus, empires of mediterranean, roman empire, 2x Africa, timor islands, Europe Advanced, ancient greece, vikings of scandinavia, trails of the west etc...)

"fantasy maps"
(GoT maps, Avatar map, Zealania, Nga Toa, Dragonport, 9 kingdons, Ancestral Waters, hoodtown, keeva island etc.)

"misc maps"
(jungle of despair, saturn, solar system etc.)

What do u think?


EDIT: another category could be "World Classic variations" for all the variations we have for the classic map. I think its 5 or 6 in total? And one more to come soon.

EDIT: or two categories more: one for maps with normal gameplay and one for maps with slighty unusual gameplay (jungle of despair advanced, oregon cities, trails of the west, water of the british isles, brecourt manour etc...)

since the amount of the maps has grown during the last months, it could be nice to have this feature (for new players?). what do u think?
and: is it difficult to implement?
