Interesting; according to Cody, this is going to be the final DLC for Troy. (And given he's one of CA's "affiliates", he would likely know.) I really hope this doesn't mean the end of the game's development, as otherwise it would imply it's going to be left massively imbalanced in favor of the Trojan factions.
The Ethiopians were a power that far back?? Wow.
I'm not sure how true that really is, to be honest. Information on them during the Bronze Age seems to be rather thin.
In the game, Memnon is a vassal of the Pharaoh, which would imply the Aethiopians (or at least those who followed Memnon) *weren't* a major power at the time. Knowing CA, however, I'm guessing they more or less made that up, albeit having based the decision on some obscure reference/source of information they came across. (CA does seem to do a fair bit of research into their subject matter, even if it's not exactly rigorous.) So whether or not Aethiopia really was a vassal state of Egypt back then, or a powerful nation in its own right, remains anyone's guess.
