Some are missing, Ag Cassablanca, quite some northern Africa maps (redko's MTO, which is Libya to Crete), MANYSH's last Libya map, Desert Online by redko..)
Seems we also miss Vanuato's 'Benghalli' by Avala, which is a small slightly offset of Vauatu's Torba disctrict, which consists of the Torres and Banks islands, Benghalli being Banks-more or less. And yes, it looks very close in RL.

Provinces of Vanuatu
Vanuatu has been divided into six provinces since 1994. The names in English of all provinces are derived from the initial letters of their constituent islands:
Malampa (Malakula, Ambrym, Paama)
Penama (Pentecost, Ambae, Maewo – in French: Pénama)
Sanma (Santo, Malo)
Shefa (Shepherds group, Efate – in French: Shéfa)
Tafea (Tanna, Aniwa, Futuna, Erromango, Aneityum – in French: Taféa)
Torba (Torres Islands,
Banks Islands).[/size]

Entered Banks aka Benghalli.

IIRC, Casablanca by agracier was WIP and the other desert maps center around Libya for redko's MTO and MANYSH's last desert map release. Anyone may step in here..of course the list cannot be complete since so many modders added maps in all regions of the world in almost every 2 weeks.

PS: Benghalli is not covered like its map dimensions, rather a tad oversized on the last pic.
