1) what mod is that
2) who's that in Egypt
3) define "manageable size"
other than that, can we see a world map?
1.) MPM
2.) Ayyubids (in this game Jerusalem based Levant-ish revolter state)
3.) when it comes to Ottomans in MPM, manageable size really is whatever size you can actually beat If they come after you, and youre weaker, youre in a world of pain, much like Golden Horde was early on for my Moscovy, they actually beat me twice, taking about 40% of my provinces.
Sure, heres the world map:
And a bit zoomed in:
At the moment im allied to Golden Horde successor states (since i force released them) but the general idea is to expand eastward, see if i can recreate the Big Game, ultimate goals are Persia and India.
1) The mod is probably MPM, a link to which can be found in his signature.
2) Based on history I'd guess the nation in Egypt is the Ayyubids (or however you spell them).
Damn youre good
