Yes, I foresee a battle-based mapped version (called Tokyo Stomp?) containing just Japan and Monster Island, where the Kaiju are not buildable and slightly heavily powered... One could play as either Kaiju or Japan only...
By the way, Ebirah now joins Gamera, Rodan, and Mothra (and maybe Ghidora and Megalodon) and as the only units capable of Kaiju transports. Other, more common units (native boats, Pteranadons, Great Whites) can only transport more common, smaller units.
Ebirah, like all or most Kaiju, will have lethal bombardment on land and sea, as well as bombard and a strong air defense.
