I would like to propose an idea of creating an ancient mod, which would take place from c.500 B.C. up to the early days of the Roman Empire (around 1 A.D.). I am proposing this because I have very deep knowledge about the period (military knowledge especially) and because some units in the game look like a lot to ancient ones (ex. the mercenary archer is almost identical to the persian archer of the greco-persian wars, the russian 17th c. pikemen looks like pretty much to the light-armed spartan hoplites, when they are red of course, the roundshier looks like to a roman legionary from the northern provinces, while the galley look like to triremes.) I think that such mod could be great. Here is a faction (all of them might not included) list of such potential mod. Greek factions
Sparta (Hoplites, Perioikoi, Helots, Cretan Archers-practically unbeatable infantry) 
Macedon (Macedonian phallangists, companion cavalry, various auxilliaries)
Athens (superb navy, strong marines, Peltasts, solid infantry)
Thebes (Sacred Band)
Corinth (a typical greek faction)
Syracuse (a powerful city-state)
Seleucid Empire (Various units, ex. silvershields, war chariots, elephants)
Western Factions
Rome (Legionaries, Hastati, Velites, Auxillia, republican soldiers)
Carthage (elephants, superb cavalry, iberian mercenaries, strong navy,suspect infantry)
Eastern Factions
Persia (sparabara, immortals, war elephants, horse archers, hellenic mercenaries,chariots,light infantry etc.)
Egypt (egyptian infantry, ptolemaic soldiers, nubian mercenaries)
India (war elephants, other units...)
Barbarian factions
Gauls
Goths (they appeared somewhat later, but still an interesting faction)
Thracians
Illyrians
Just an idea
Opinions...?
