Tiberius the Macedonians definately had War Elephants. That is how Pyrrus of Epirus won early victories against the Romans. The War Elephant became a part of Macedonian Warfare.

However you are correct, the Greeks never abandoned their version of the Hoplites in favor of Macedonian Style Hoplites.

I didn't download the mod, but I like some changes, but seriously do not like others, like the Greeks using Macedonian Style Hoplites, the Thracians where much closer to Greeks then Barbarians so their having theaters makes most sense.

I definately like the loose confederation idea though, and I like the non Mercenary Illyrians, Cretans, and Rhodians, although they do seem to have limited use because they can only be trained in one place.

Is there a way to download that mod and still be able to play the original game stuff or is it one or the other?

You can probably guess, I know more history then gameplay from the noob question at the end (yes I admit I'm a noob )
