Yeah it was. You started in a reconquest war for Albania, could day 0 dow one of the opm beyliks for another, in a month dow a 2nd one, in 2 months dow the 3rd one, in 3 months dow candar, in 4 months dow Byzantium using city of world's desire mission. End the 4 reconquest wars with full annexation, take Byz capital while also vassalizing them (failing the mission but avoiding admin costs and freeing greece for conquest and able to return cores to byz from the islands). When they're done you'd have a great start on income and just needed a few years rest for WE and manpower.
It is a bit better now, though, even though you can't single out every nation in its own war. Starting income is a bit higher and I could get a +3 admin advisor right away. Late 1400's I had temples, constables, armories, and training grounds on every province.
