Started as Ottomans:
Barbary States were allies & protectorate at start, which is never good as they are hated and are at war with everyone. Got rid of them and blocked all there trade routes at sea, should have a decent sized army marching towards them within 10 turns (Cairo starts with a lot of good buildings)
At war in every direction but Austria, and I've managed to calm Russia down. Still some pretty big fights coming my way from the south & north though. Allied with Sweden, Prussia and Poland-Lithuania, will help in the march north.
Ottoman army seems very hard to play, I've got a good tactic, depending on enemy confidence (usually only works if I have a full army, as they tend not to push) using 3 lines - Line Inf (Either Ordo or Elite Janissaries) Janissaries (Melee) followed by horse archers (arrows go over top)
Static cannons are really annoying me, they've got wheels and a 4 man crew, push it you fools!
