The Ottomans had Turkish, Greek, Slavonic as state cultures in EUII, which was historically correct and made gameplay sense.
In EUIII, however, they have Turkish and Arabic cultures, which makes neither historical nor gameplay sense.
Ottomans were founded on Byzantine heartland land near Constantinople, and expanded towards them from day one. They ruled over Byzantines and converts. They were related to the Byzantine noble families and involved in their politics. They adopted Byzantine traditions and institutions. They took over the Byzantine geopolitics and "mission" and ruled over Byzantine lands with ease. All Ottoman historians consider them locals, not outsiders to the Byzantine world. In comparison, they started ruling the Arab lands more than two centuries after their foundation (founded 1300s, expansion into Arab lands after 1510s). Ottoman rule of the Arab lands was also indirect, while they ruled Balkans and Anatolia directly. Same with the ruling classes. Almost all rulers came from the Balkans and Anatolia and very very few were Arabs.
As such Turkish should be in the same culture group as Greek, Bulgarian, Albanian, Serbian, Armenian etc, and the culture group should be called Byzantine. This change would not only be historically accurate, but also help the Ottomans (who performed miserably both in EUII and EUIII) perform better in the game and make Byzantine fanboys happy at the same time.
Failing this, Turkish should be in the same culture group as Tatar. That makes infinitely more historical sense than Arabic, given their relations with the Crimeans.
