Thinks are not really that badThats a very funny map indeed
So its not only heavy plains, the near terrain contains also plain tundra, snowland and plain desert as well. There are only 3 different luxes - crabs, elephants and marble.
No near Ai - thats pretty bad for morocco UA.
No CS too.
Spoiler :
There are lake Victoria west,If you go south-west you will find furs and pearls. If you go north eventually you will find 4 unique lux I think, but you did not list all drawback ether, may be too early.
