Yes, I know, but as I said in my first post not all the factions are from th same time. It was a compromise to get a Roman faction in. Remember there wasn't a Rome at the time really so I had to find another name, and calling them Latin Tribes simply isn't good enough as then I would have to do the same with all kinds of tribes. Something had to made special about them.

If you notice then Albion is more or less Camelot, and the Etruscans are too early, they didn't come to Italy until about 8-700BC. But those are compromises to make the game fun. And there most certainly wasn't a Thracian faction.
If I had to follow the times completely then we would only have factions to the very east, not fun in my mind and would leave certain faction with great chances by just going "Hey guys, screw you were are going west." And who could stop them?
