I'm not bashing it, I'm giving my opinion about it. I know how to model, texture, and look up and use reference material to make an unit, so I know what I am talking about. There is plenty of material out there; images, descriptions and objects. All of this is a subject of interest for millions of people; they go to museums, read books, etc. To me it would seem a no-brainer to make all the units accurate as you would get those people more easily interested and you can save on drawing all the concept art as it is already out there.

Yet, for some reason CA decides to come with an experiment in which the artists are giving a history book let them flip through the pages for a minute and then let them make the units based on what they can remember. Of course not, but they are making their units based on their own imagination and taste. You cannot disagree with history but you can with interpretations of history and CA's one is deviating far from the source.

NO GAME IS PERFECT.
So my point being: the unit design can be perfect. The modellers need to have concept art before they can model. Either you buy a few history books or let an artist draw concept art. Practically every mod which has more realistic models gets praise for just that. The fans want it, so why make "fantasy" units? I don't know, do you?
