The second battle I'd like to look at is Asculum, 279BC, which was fought between Pyrrhus of Epirus and his Italian allies and a Roman army under the Consul Decimus Mus.
I considered the other Pyrrhic battles, but unfortunately none fit the available terrain. The battlefield featured some hills and woods. I think we could add some of these to the Zama boards; perhaps adding some extra boards, or freestanding hills. We would want to fit Pyrrhus' camp in, too, as this played a part in the battle.
The troop types aren't as varied as Chaeronea , but a game would include a very large number of pikemen, some elephants and a large number of Roman anti-elephant carts, which would be very interesting to model. It would be a good one if we could access Aventine and Craig's Romans again; and would tie in very well with Aventines' projected Tarantine range. I'd think a 3m long pike phalanx would look very fine!
