Don't know if anyone else has tried this yet, but I just fought a custom battle in RTW after installing BI.

It was on grassy flatlands, with 6 Macedonian Phalanx pikemen defending against 6 Seleucid Phalanx pikemen. The Seleucids were under AI control, but I didn't alter the deployment of the Macedonians or issue any orders to them throughout the battle.


Setup


It dropped spears as it approached, and began obviously pairing off against my units.


Looking Good


I've been waiting years to see this!


Phalanxes fighting properly!

The Macedonians won, but suffered nearly 50% casualties (in my excitement I forgot to screenshot the final score) so Phalanxes are still a defensive formation. I might go see how it behaves when theirs cavalry and missile troops about now.
