KH is often the most fun cos you can run the campaign using regional and/or city state armies, ie Sparta or Athens. Hoplite is a very strong unit, can really only be beaten by elites. Peltasts are extremely versatile (and use swords). use light infantry to flank, but dont trust Therophoroi [sp] etc on their own too far from the general. KH realyy do fight best in a line... Cav are for chasing down routers only. Later you can bring elite cav and phalnxes. But that makes things very easy.

Oh, and the FM is ur best reserve, alive general = win.
