I have a minor gripe about Ottomans AI: in my experience they always beeline Iron Working and Siege Foundry, usually building a lot of spearmen and trying for one or both of Halicarnassus/Statue of Zeus on the way there.
I don't think the +3
on the Foundry and the little science it could net at that stage (because they already built an army of spears and catapults are not unlocked) matches 2 earlier trade routes, possibly delaying Trade by ~40 turns and sailing by ~60, that's a lot of trade opportunities and instant yields missed, with archers+warriors being enough to fend off barbarian raiders.
Now it might be that I only notice them failing at early wonder-whoreing plus warmongering (two things that don't go well together not even for deity AI, when they lack Ancient hammers or UU) when they spawn as my neighbours, and in those cases it's actually a good option to build a military first because as a player I'd be pillaging their caravans while assaulting the wall-less cities should they focus on the top part of the tech tree, but it feels like they aren't playing at their strength in the first ~50 turns, and at least Trade should be given an harcoded higher priority.
