I typically struggle at Monarch, but for once I got a good game. I rolled Suleiman with a perfect starting location (capital had corn, gold AND gems, 2nd city got access to bronze) and found myself on a continent with Pacal, Elizabeth and Justinian. Pacal, poor chap, was ridiculously close and still expanded towards me, while building Stonehenge. The last Axe attacking his capitol earned me a great general, who created a super-attacker. This super-unit got lucky again, finding a big, fat English city with just one archer to defend it 
In the meantime, Justinian proved himself to be a decent AI - expanded, teched, occasionally competed for wonders, becoming close second in both land and population. The chief difference between our empires is that I skipped most of mediaeval techs in favour of Liberalism and Gunpowder.
Now for the question: would You advocate going with janissaries vs his longbows? I have perfect time to prepare, being set up for two consecutive Mausoleum-powered golden ages (Taj Mahal finishes in 1 turn and there is a superfluous great prophet waiting).
