Unfortunately it would spoil some secrets if answered properly. But I will say that we have spent a lot of time (especially Qwerty and Stormy and others) working on getting a more realistic Arabian peninsula for 272bc. There will be some unique buildings there (at least four on the peninsula that I can think of) too. We just wish we had someone who would model and get functioning correctly some palm trees for the battle maps (besides those that clump around the little "oasis" thingy).
