If you remember Feudal Wars (and how it failed), the main developer didn't give up trying to make a great RTS. I'll try my best to follow this game... especially the dev logs. It has one entry where he praised 0 A.D.'s artistic realism while stating that it has become detrimental to gameplay (Forum-ception: His article quoted a thread on this forum, and now I'm indirectly quoting him back).
