3) For animations I created a brand new type of animation (medium infantry) for Iphicratean troops and I changed a bit the wonderful work of Moonhoplite so for the phalangite animation credit goes there..
4) Generally there are severe caps for dated troops.I have unlocked the thureos hoplites for all Greek nations but the old school hoplites have a cup of 6.Spartans have more hoplites but less to non modern troops and of course pikes.Spartan troops have also very increased creation times.(4 for hoplites and 2 for pikes) representing the numerical weakness and lengthy training so you got to plan ahead..They cost more for creating representing this costly and time consuming training but upkeep is very low representing Laconic way of life..Also citizen hoplites and militia hoplites and Female Spartans are kept only as garrison troops.
