These are for EE2 vanilla version; one problem is that I don't know how to count max players for a map.
1. Dominicana
300x300
This map includes Dominican Republic island and some fictional islands which surround it. Perfect fit for landing/island defense scenario. The main island terrain makes it impossible to land in some places (basically, 60% of its length is not suitable for amphibious assault), so only some shores need to have lines of defense.

200x350
Detailed map of Korea, also include small part of Chinese territory. Quite difficult terrain makes armies deployment somewhat challenging; great for ambushing your opponents. Places of the main cities are highlighted by 'under building' type of terrain.
Spoiler
326x326
Map of the late Byzantine Empire (although Constantinople made bigger, so it's not in a proper scale). The number of territories is intentionally small, thus supply chains are always long and armies need to cover long distances. Can be used in epochs from The Roman Empire up until Gallipoli campaign. Places of the main cities are highlighted by 'under building' type of terrain.

380x200
This is a wide map that covers a small part of North Africa. Includes a territory with dunes, that will slow down armies movement.
Spoiler
200x300
