I just finished my Agamemnon campaign. Here you are my remarks.
-Units are cool and versatile.
-Different hero/faction abilities are cool. Like the Aeneas the necromancer.
-There are too much centaurs to the setting especially in Greece.
-Sieges are too easy to start. All right, units carry ladders in their pockets, but sieges in the early ages were hard. A compromise would be if units use less ladders. 2 or even just 1.
-It was disappointing the siege of Troy didn't require Troyan horses.
-It was very hard to orientate on the minimap from turn 1 to turn 120. At the beginnings it was impossible, later it became very hard. My faction color was light blue and the sea is dark brown. Quite nonsense. Sea should have colors which reminds to the sea. Or if brown from some bizarre reasons, it should be very-very light. There must be a sharp contrast between land and sea.
-Apollon in the myth was the main supporter of Trojans. Storywise it's quite bizarre he can help the Greeks AGAINST Trojans. Aphrodite is a similar case. Hera and Athene should support only the Greeks. I hope the new gods will resolve this issue.
-There are a bunch of trinkets but very few weapons for heroes.
-Heroes and agents already in the game also became children of Zeus when they are placed on the map from the unused pool and when they return from and injury (if I remember correctly). This must be a bug.
-Slings are too weak compared to the ancient reports. Slings hit hard and had a far longer reach compared to bows. Bows are too good in this game. To be weak against armors is okay but even bows should be weak in this case. Okay it's a game they won't but slings should be stronger still. Maybe a bigger difference in range. Bows should have range of 150 for example.
-Light spearmen should wear only a tunic and maybe a bronze helmet. If someone wears bronze he should be tough. I think on the weakest spearmen in striped bronze cuirass. In the bronze age light armor didn't exist.
-Medium tier units shouldn't have pauldrons. This way they would be easier to differentiate them from heavy units by sight.
-Archer heroes should have Scythian horn bows. Paris on pictures holds just a decorated wooden bow in the shape of a reflex bow.
-Units cannot attack at road bends. They march in a line and only a few attacks.
-Chariots are slow. Light infantry is able to outrun light chariots many times. Especially when they want to disengage from melee.
