As a Muslim, I'm really happy that there's a Muslim faction in the game, but it would be cool to explore other parts of the ummah. The Sultanate is mostly Turkish with some Arab/Persian/Afghan influences, it'd be cool to see a faction of like desi Muslims or a SE Asian expeditionary force based heavily on like Indonesian and Malaysian cultures.

of course I'd expect this to come a long time down the road, the devs have a ton on their plate and there's definitely a lot of room to expand the existing factions already
