ally lithuania, hungary; take mission to take western prussia, take it, then you should get events, i prefered to take only western prussia as it anyway vassalized teutons, they can form prussia so you will have nice little march; if livonian order was still their vassal, now its yours (they can form livonia and are too far and useless lands for early game to care); on .03 hotfix there is still bug where as you declare war on bohemian silesia vassal bohemia is not dragged to war so use it (with relations improve advisor, ae will tick down faster); remember to integrate mazovia and build u warsaw (warehouse district, town center rank 2, university (as much as you can, as rest of provinces around will be shit then your art power should be high with other buildings and some burghers), art corporation and first trade and workshop ones) <- with these buildings my burgher gravity was ~20 and warehouse district speed up growth; for ideas quality is must have and do your NI asap and dont forget to have 1st row big as combat width (+2), especially if you go to war against ottomans
