This game does have historical roots. We've done our best to represent factions in the peak of their respective empires. Pitting them against each other in that state alone is unrealistic, but that's part of what makes this game fun. Likewise, including eastern civilizations is not an attempt to recreate history. It's a channel by which to re-imagine history. What if geographic complications hadn't prevented Rome from wanting to take over the Indian empire (which, it should be noted, is represented in our game several centuries apart from the Roman faction)? This game won't prevent you from recreating history's most famous conflicts, but it will permit you to explore your creativity.
