This is one of the Hat sets I still eagerly await. As said, a nice little formation could be done with them. And with the plain shields, as opposed to other offers coming with moulded imagery. I prefer the plain shields, because with the proper decals, we can have formations from different city-states.
Itoo believe there is a need for hoplite. Yes other companies make hoplite but half of them are swordsmen,and the rest brandishing their weapons all over the place everywhere but forward (not bad if you want to create a set for a vintage 1950's or 1960's swords and sandals movie but not so good if you want a realistic looking phalanx bristling with spears). Personally I like the Archaic period when the Greek Hoplite was making his reputation because of the great variety of opponents they were able to meet and fight against as well as each other. By the way, that time period overlaps with Hatt's
assyrian army and some of their auxiliary troops could be pressed into service with the Greeks as well.
