Well maybe if a certain Basileus hadn't burned down the palace at Persepolis we wouldn't have that problem. :p Well the clearest indication would be pottery, wares and coins from the different parts of the Empire in India and in India would be the clearest indication.

AVSM I said that though. :p The reason being he probably felt he shouldn't go far beyond the borders of Persia. He probably would have kept going and eventually the Pacific. If Alexander could turn Tyre into a Peninsula and was willing to cross Gedrosia I doubt he would have considered a trip into China to be too big a task.

Oh! That makes a lot of sense actually and would account for the bit of Africa in the map I showed in the OP where Africa and Asia are connected!

Maybe for you, but satisfaction is relevant and a cartophile like me likes huge game maps! You mean kind of like the one they have in EU III and HoI3? When you have a more realistic set up of course your empires won't grow all that large :p I guess they figure if you make the game too realistic, the level of difficulty would turn people off.
