126x126 sized map for 8 players, which happens to be a remake of Westwood's multiplayer map "Marooned II" from the base game. Plenty of building space and resources to utilize.
UPDATE: After further testing, I thought it'd be better to add some bridges across the water, so the players who start from the south can move across the bay more easily to collect addional resources, and to offer more offensive options for quick ground attacks across the map.
