The Punic Wars
The struggle for domination between the two great rivals of the Mediterranean, the Punic Wars inevitably conjure up images of Hannibal marching elephants over the Alps, or, for people a little more widely read, the Roman Army being crushed to death at Cannae.
Further to the basic Romans and Carthaginians, I have also put together a Successor army which can be used to represent Macedonia, Ptolemaic Egypt, or the Seleucid Empire.
The DBA rules have allowed me to fight endless battles with these armies, and I recommend them to anyone who just wants to paint a small army and start gaming!
Above:  Part of my Seleucid army.  Pointy enough to deal with those pesky Romans?  They sure hope so!
