I don't think the goal of this multiplayer battle mod is to be historically accurate. It seems more about historical evocation I would say (which is not a bad thing if it is assumed).
We have a battle re-enactor writing up a combat manual for historically accurate rules of engagements and roman tactics for clans, we also have a historian who is guiding us through the process of this mod. All our assets will be revised to ensure the best historical accuracy possible before being ported; We may have one or two assets that came after in the time of Augustus, but it's not historically impossible for say the Centurion helmet we made to be there. It's also incredibly simple for us to make a dozen more period accurate helmets in a few days. We are also doing historical battles for the mod that include the Battle of Alesia, Battle of Vosges, Britannia Landings, and more.
We're naming units based off real legions, and armies of other powers after the names of their gods and tribes.
So no, you're wrong there.The goal is historical accuracy whether you think so or not. Evocation is also the goal as we will have a battle mode that let's players play in non historical battles with the mechanics of our mod. Anyways, no game/mod will ever be 100% historically accurate. At best, they're all evocations at the end of the day.
A better example of a mod in which the goal is historical "evocation" would be a mod that does not replace vanilla assets with assets based off historical references; And simply retextures native assets to evoke the feeling of rome. A mod like ours in which the goal is historical accuracy, makes assets that are based off historical references from the time. An example would be say, like the gladius we made that is Hispaniensis style vs any other style. We take into account those small little details mate. Driven by a goal of historical accuracy.
