personnaly out of all the factions i think russia is the best.people argue that the russian ecoenemy starts bad i but if you can bolster econemy in trade. also declaring war on prussia in the first turn gives you more regions quickly to use since prussia not that hard to beat. second you have time and space if a war goes badly. and due to the vastness of russia its hard to attack plus attrtion.also beating the otttaman army is not that hard sine they have bad genreal and to much orta peasent leavy.once whiping out two gret powers just invade austria from both sides.on the way make a lot of vassals to bolster econemy and to act as buffer states. with two great powers dead its not that hard. also vassal mean you get 50% money plus money from trade. after that defeat denmark and sweden and just march west. reason its my favorite is cause of easiness anf fun even in very hard. however im sure your all gonna argue but it will be fun to hear other reasons.
