The Byzantines are one of my favorite Civs and even if they don’t change, I still enjoy them due to their history and diverse culture. But since other people constantly ask for a Byzantine Buff, I’d suggest a few radical changes (since this game is ever evolving) that will bring a few civs more in line with their historical origins and make them stronger in uniqe ways:
I always find it funny/odd that the Byzantines are suppoesed to be a defencive civ yet everyone in the MP comunity complains (Never uses them) becaues they get easily over run in the early game. Thus here are my suggestions for civ alterations:
Current civ alterations.
Vikings.
Have Vikings lose free hand cart + lose Arbalerster but instead they get Halbedier,(NB!) have their longboats be able to attack as well as transport units (Infantry only) (loses transport ships but they have non attacking Longboats in feudal age.) and gift them cheap trash units.
Castles cost change to 450 stone and 300 wood OR… Since they get Halbs change their unique tech Chieftains to allow Beserks to be made in TCs even after all castles have been lost.
I’d enjoy raiding coastlines and rivers using longboats to transport infantry and skirms to the shores of my enemies.
Byzantines.
In turn have Byzantines lose Hand cannoneer, bombard cannon and bombard tower , [to have them not become intensely OP and these forms of warfare was much more used by their neighbours (Italy) and enemies (Turks)]. Trash becomes more expensive and Imp becomes more expensive but Civ gets free wheel burrow and free hand cart. (For even when they were still the Eastern Roman empire, they already had WB+HC)
Byzantines get a unique tech in the Feudal age barracks: Justinian Reforms - Sword line +1 Melee armour from castle age.
(Optional) Enables the technology of Varangian Guard from the Feudal age.
In Feudal age , Byzanitne army gain access to a special unit in the Barracks called the Varangian Guard. - Expensive , slow moving but difficult to convert with a limited build amount.
Since the Byzantines are a Defensive civ, the Varangian Guards can have a high attack boost when in the vicinity of a TC or Castle but outside a certain radius from these buildings the VG should loose the strong attack bonus and just be as strong as a normal Man at Arms/Long Sword/Champion.
(Highly loyal guards of the Emperor) To defend against early rushes , but since they are expensive,slow and limited, you will have to think strategically as to when and where to deploy/station them.
Unique Castle techs remain Logistica and Greek fire.
African ,Mezzo,
African and mezzo civs should only have canoe navies. Able to fire arrows ,fast ,agile and only using 0.5 pop space but they don’t have access to Gally line, nor cannon. Gallons. All canoes can carry/transport 3-5 units. Don’t have access to fire ships but get fire canoes that shoot fat covered fire arrows (Fat burns intensely hot).
