Here is the official Alexander EB Thread
Also, you can PM my good friend Lz3 for any help - he'll be glad to assist you.
Oh, and this is the 1.2 modpack, in case you haven't found it yet. It does have Darth Vader's stuff in it, so you'll be guaranteed to get the best AI possible. However, if I were you, I would not install absolutely everything, especially that city mod, no offense to MAA. I think it is a bit pointless, since EB is alternate history. True, some places, like towns in deserts that do not have an access to sea cannot grow beyond a certain size, but all other cities should, if any changes were made to history, which is what happens in EB, since you are creating alternate history there. Also, the phalanx mod is slightly questionable, since it resembles the old vanilla phalanx at times, such as when it is walking. I still think it is great though, especially how it fights, which is absolutely stupendous in comparison to vanilla RTW and vanilla EB.
