Exactly! you CAN fly them down south to French and UK parts of Africa. but why would you do that? those territories are out of the way, and not strategic for either side. Which sounds smarter 5 fighters in France? or five fighters in a territory south of Algeriea?
Which sounds smarter 5 mech infantry in Manchuria? or five mech infantry in the Solomon Islands? Since mech infantry don’t get any advantages on islands, should we ban them from landing on islands?
Good point, but I think it’s simple to remember no ground units, only air units. It would work like sea zones except with no building ships allowed. You wouldn’t need a bunch of different terrain types, just sea zones, land territories, and flight-only zones.
Everyone, your points about the Himalayas are taken. So we could have four different terrains. Land, sea, air only, and impassable. My points about the Sahara still stand though.
