Not enough. They are maded by 'franchises'. I expect something separaterd from 'third-party' universes (maybe Wesnoth in 3D RTS). Age of Mythology was too boring, because of too much simple antic structures, disguisted design, etc. RoN:RoL - that is good example of not ordinary fantasy without stupid 'meduses', 'vikings' or another popular cliche. And I'm not brony to accept Pony... The second reason to make fantasy style is no needs to be historical accurate. Especially in the naming. 0 A.D. as I understand it is 'fiction' 0 Anno Domini? What kind of 'Domini'?
The third reason to make fantasy - is that the historical games, especially that bronse age, feels not like game, but like Provincial Museum (of Archeological Fakes). I'm sorry, but known history is not science in classical description and was allways politicized, prestigious historians can be bribed and promote fake opinion by decades. How much more antique fakes should be revealed - no one will know. So... Interesting things, I would say. 0 A.D. is already kinda semi-fantasy game, but not so spectacular as RoL. If you understand what I mean. I hope, developers are sure in the sources of which they're copying armor and weapon.
