Well IMO, this map should be a majority (55) or less. The stalemate lines are very easy to set up, particularly in the middle of Asia running north and south. In addition, the sea zones are so.big around Africa, that it is easy to stymie an enemy fleet.
For example, looking at the game I am in where I am Germany:
I have destroyed France, Denmark, Russia, and almost byzantinum. I control the British Isles and most of mainland Europe as well as part of western Russia. And yet, despite my dominance and being twice as large as the next power, I am only halfway to tjensolo, and 60I scs looks to be almost impossible to reach. 55 would be more accessible, but still quite difficult, which is probably the type of balance we want.
