- I put a special care to it, but there's always some problem with cities.

- I could not get a clear information about Roman-Persian boarder 591-606;
  I know it, about, when it comes to Syria. But Armenia. My only knowledge about it
  is that it went much further east than earlier one, which I know, and yet further
  west than the one after the last Persian-Roman war, which gave all Armenia to the
  Empire. Another thing is that I read in one book that the boarder was moved somewhere
  near Van lake. But this sentence seems to mean that its shores remained Persian

- I don't know the capitals of barbaric kingdoms in Gaul and Britain. I'm not sure at least.
  Will check that.

- I simplified some historical events; like Persians declared war in 606, I made them do it
  right after Focas revolt.

- I needed a civ that stretched from Ukraine to Transoxania, to balance both Persians and Slavs. As such civ 
  would be an obvious inaccuracy, I decided to make one more, and created Khazar civ, which not only posesses
  in my game lands that it never did posess, but also is a might 30 years before it became one. Of course, I could
  have made Bulgar civ, but it wouldn't make sense, as it disappeared early in the game. I could make them and Transoxania
  states Barbarians (and I'll perhaps do it, if I make Khazars playable), but protecting them from being conquered by others
  would be an unnecessary expense of effort and event space. Also, I'd have to defend tiny Khazar civ then as well. I added
  entire Transoxania to Khazars for the same reason, also for balancing Persians in any way.

-I moved Tarsus a bit for strategical reasons
