I'm in the year 1790 on m/h. First I did nothing, as usual. Searched only for tech (military and industrial) and built my economy. I allied with Russia on the first opportunity. Then I made a mistake (it was 1715 or so), I joined Hanover in her war against Sweden (both my allies). I thought that Sweden had attacked Hanover but it was the other way round. To complete the mistake I also started war with Hanover to get Denmark from her. The next turn Poland invaded me. Fortunately Russia remained on my side. To my great luck Sweden declared peace (they had nearly ruined my economy with blockades). I destroyed Hanover with great problems (really huge army) and took Gdansk and Warsaw from Poland. Some turns later they accepted my sue for peace. Courland remained at war despite my pleading for peace, so I got rid of her.

After this a long peaceful time followed. Then I attacked Saxony and Austria declared war but did nothing ever since. I invaded parts of India and allied with Maratha. In 1755 I declared war on the UK (my Indian sepoy army conquered London) to free Scotland and see highlanders after Scotland would have rebelled against me (they did but highlanders never appeared; are highlanders other than Black Watch in the game?). I invaded Morocco and the Pueblo Indians and some German states, mostly from boredom. And so on. I could have easily conquered Europe but why should I?

The only problematic situation was during my war with Sweden, Hannover and Poland, mostly due to own stupidity and greed.

The best moment was when my people rebelled and I managed to get rid of the repressive and authoritarian Prussian monarchic government.
