Right now, there's a Hellenistic Sparta and a Later Hellenistic Sparta, but the Achaeans only come in one variety.

The Achaean variety requires them to take 5 pikemen, to a maximum of 16, whereas the only the Later Hellenistic Spartans get to take pikemen, and at a maximum of 8.

This is very strange, because the Spartans employed pikemen decades before the Achaeans, and fought a major war against the Achaeans before the latter employed pikes. King Cleomenes III of Sparta had certain revolutionary policies, and one was to take 5,000 picked men and train them in the use of the pike (right now they're just average in FOG, but okay). In the Cleomenian War that followed, Sparta fought the Achaeans in a number of battles, and the Achaeans did not have pikemen. According to Plutarch, it was later that Philopoemen reformed the army so that the Achaean League would make use of the pike.

In Field of Glory, though, the Achaeans have pikes before the Spartans, and in greater quantities. As far as I can tell, this is clearly against the historical record, as in reality the opposite was the case. This problem could be solved by making the current Hellenistic Achaean army be "Later Hellenistic Achaean", and make a new, thureophoroi-based army be the original, Hellenistic Achaean force. Then, rename the Hellenistic Sparta army list to "Early Hellenistic Sparta," and rename Later Hellenistic Sparta to plain old "Hellenistic Sparta", thereby illustrating that the "Hellenistic Sparta" army list should fight with the "Hellenistic Achaean" army list as well as the "Later Hellenistic Achaean" army list (if you keep it as "Later Hellenistic Sparta," it sounds as though pitching it against the "Hellenisti Achaean" army would be an anachronism, but really the two armies really went at it when the Spartans had pikes.)

If you want primary sources, I would be happy to cite to them for you. The final paragraph is only a suggested fix; I am sure you can figure something out more suitable (assuming you agree it should be changed).

EDIT: I guess one source of confusion is that the Hellenistic Achaean army list describes the army as being for 146 BC; if 227 BC is later hellenistic sparta, then something is awry

Bug Report:

For some reason, I can't select 2 Veteran Armoured Cav and 1 Armoured Cav in the Later Hellenistic Sparta army list. I must take 2 or 3 from one of the possibilities, no mixture of cavalry types is possible. Kind of confusing

EDIT: I can achieve certain mixtures by playing with the general button, because making a cavalry general will force it to put a 1 in the empty category of cavalry
EDIT 2: Can't do it with the Hellenistic Athenians, either.

Addressed the cavalry choice option as part of 1.2.15.
