Thanks Civinator, I'm glad to join CFC!
I understood and thank you all for the clarifications and guidance!
I know the C3C problem in this matter, but I thought that maybe it can be fixed in RARR...
As for the "special" units of each civilization... it depends, what you want to do about it!
If you want the units to be exactly as in history, I think we can help you by searching and making a list of these units, for example, Rome:
1. Rich soldiers = cavalry
2. Medium soldiers = heavy infantry (hastati, principes and triaris)
- The Hastati were the front-line soldiers, equipped with helmets, oval shields, swords, throwing spears and a brief chest protector.
-Principes, a bit richer, had better equipment, usually chain mail shirts and shin guards.
- The triaries were the veterans and represented the last line of the legion. They were thrown into battle, in desperate situations and had the role of heavily armed lancers.
3. Poor soldiers= The poorest members of the republican legions were velites. They could only afford simple armaments. In particular, it is about spear throwers, archers, slingers. They served as support troops.
And so on...
I personally think that the connection between a resource and a special unit must exist! You can divide the special unit into two stages, one soft (without the resource) and the other heavy (with the resource)!
Perhaps the construction of certain specific units, which only another civilization owns, should be conditioned by a certain resource... For example, the Sherman tank, or the Russian T, or the German Tiger... the Spitfire, etc
One more thing... I don't know if you have this in your plan, but... maybe an imbalance regarding the units of each civilization... in this way there will be few similar units... I think the confrontation would be more challenging!
Sorry, if I went a bit beyond the original topic...
Thank you for your attention!
