Speaking about strategy gaming. I recently got into Empire Total War at last, and have already pissed every single nation in the game.
I went as Prussia, figuring that having the best ground army of the time under my command would benefit me greatly in my run for World Domination ( seriously there is a game mode where you have to take over almost the entire world ). No matter that in history Prussia was almost completely annihilated by Russia, Austria, France and Sweden fighting against it, as the tiny voice in the back of my skull kept shouting.
A voice which I silenced, along with any sort of common sense that I had. My first turn was marked by an invasion of Poland, since hey Warsaw is RIGHT THERE and undefended and a takeover of Dresden. Of course ignoring Austria as Prussia while you invade Poland is like ignoring a rabid bear whose meal you just stole, but I could care less. I had taken the Polish Capital and had gained.....nothing. Seriously the research building had to be rebuilt and I could not tax the people there since they hated me to hell and back.
Still, with Dresden, Warsaw and West Prussia ( which I took over in 2 turns ) under my control I figured I would just destroy Poland while Hanover ( my ally ) would prevent France from attacking from the west.
That is until Austria declared war.
Now common sense would have declared that I give Warsaw back to Poland in exchange for a peace treaty while I marshal my force to crush Austria to the south. Common sense eluded me. When I get stuck in something I sure as hell ain't pulling back without a fight, and I wasn't about to lose Warsaw regardless of no benefits.
So, with a small quarter of my army I invaded Austria while the rest garissoned Warsaw or marched in the east on Courland ( small nation, protectorate of Poland ). I took Prague and then bluntly told Austria to **** off from the war in exchange for their city back. Never mind that I could have used Prague to actually get income! Hell no I was giving up Warsaw.
Then Bavaria and another minor nation declared war on me. So I marched on them as well to the west!

Meanwhile the Poles had marshaled a massive army to take back Warsaw.

Which I completely crushed....

...before getting attacked by another, LARGER one!

Things did not go so bad from there. I was able to conquer Poland, Courland and Bavaria.....before the Ottoman Empire declared war on me...

....and with them came Russia and Austria. I could win virtually every single battle against them, but attacked on so many fronts I could not hope to win the war. Thus I gave up and started a new game where I waited one turn and then Poland offered an alliance against Austria...
Fate is a ****.
