Why do the Byzantines get all the historically inaccurate fun?
Why isn't there a gigantic amount of potential gameplay about the Muslims reconquering these areas? Seems unfair, s'all I'm saying.
Game is made by Europeans, to be more specific the "westerners".
1.) Most of the "westerners" (in this case the ones on the island and ones across the sea) are obsessed with Rome and Romans (for some reason). In EU3 which is a game focused on age after "the" Rome, the closest that you can get to "the" Rome are Byzies.
2.) Most people in general like people/countries/alter egos in general that are, in certain context, considered an "underdog". Nobody can have too much fun loading as France and uniting it, and than brag that they have achieved something. But everyone who manages to survive and thrive as Byzies (even to turn the tables around) can be proud of what they have done.
So out of combination of 1.) and 2.) an interest (or desire) to play as Byzies was born, hence when EU3 was under development, one of the devs sat down and wrote these missions.
Writing missions is not always as simple as it might seem. It doesnt require too much time to do on its own, but it does require lots of time to debug it (to make sure that it works).
3.) Byzies are Byzies and Granada is Granda. Nothing more has to be said. Its not fair, but it is what it is. One was given more attention, other was put there to get killed within 5 years of game start.
