Chiming in just to agree that this is some amazing pixel art. Some of the small details are especially neat, like the different regions having different styles of farmland/fences/etc and the different ships, animals, and riders - and even just having nice, intelligible townbuildings when three or so fit comfortably inside 10x10 pixels! The framing of a menu for a strategy game is great and fitting presentation too, although the map itself seems like it could also suit a classic computer RPG adventure.

...Also I'm a little curious where that one camel rider is headed in the southeast corner Secrets of the desert?
