One small request; It is not Constantinople it is Istanbul!

[Unreal]

This is a story driven game, so calling the city Istanbul when, in 1839, it was known as Constantinople just makes the story weaker and less believable.

If you are, as you say, very sensitive about this then that is your problem. I'm sure the developers had no intention to be insensitive when using the name but were just trying to be accurate to the time period the game takes place in.

I 100% agree.
