Have you seen that Immortal Miniatures intends putting ouit 28mm Greek Hoplites of the Persian Wars era in plastic this spring?
"What is surprising is that the Greek city states, in face of this
obvious step forward that beat them every time, kept using the short
spears and thinner phalanx for at least the next hundred years."
But it wasn't an obviois step forward. It wasn't Alexander's pike phalanx which beat the Persian Empire but his superb horse - every time. In fact in Asia when the pikes came up against greek mercenaries (at Issus) they were beaten. The mercenaries crashed through them but when they saw both their Persian horse flanks had collapsed they kept going forward to the nearest port and embarked for Greece. Don't take everything the pro-Alexander ancient writers say at face value - winners always write the history - but check out what actually happened in battle. It was the Companions going for the opposing general that won Alexander's battles.
