I hope the usefulness of information makes up for the lack of quality. The other 2 videos have much better quality I promise.

When you start the game:
- Council missions
- Marriage & alliances
- Ambition
- Then check if you can put your succession law on ultimogeniture and realm laws on as much centralization as possible and medium crown authority.

Afterwards, look for the ways you can take land:
- De jure claim
- Personal claim (fabricate claim from counselor or inhereted)
- Support the claim of one of your vassals
- Or religious wars.

Playing as the King of Wallachia in 1310. Having a really bad RNG but eventually rising back up. Basically, this game was Murphy's Law, everything that could went bad went bad. I think this video is better than a video where everything worked great, because not everything works great in Crusader Kings 2, and that's part of the game.

The video ended right after I declared war on Transylvania. After I took that county from Transylvania I had enough money & prestige to revoke the titles of my other counts in Muntenia and take their territories myself. Then I gave the Duchy of Oltenia to the vassal who liked me so the Count of Oltenia who hated me became his vassal instead, so I had only 1 vassal with 100 opinon of me. Then I went for ultimogeniture. And Kiev now wanted to be my ally.

So with 3 great allies meaning a lot of support. And owning the 4 counties inside my capital duchy leading me to have 5.600 troops. I was ready to take on Moldavia on a De Jure war. The crysis has ended.

Unfortunately, the video ended right when I declare war on Translyvania, right when I started to rise back up. But it's still a great video about survival in bad moments in Crusader Kings 2. Because Crusader Kings 2 is all about the RNG

This is the second and last part from my playthrough with Wallachia. Although I do explain things as I'm playing the game, this is not a tutorial as everything needed to have a good basic understanding of the game was already explained in the videos with Mumu and Wallachia part 1.

I began from where I left off, going through the bad RNG and then consolidating my kingdom, and with a kingdom consolidated and alliances I was able to take down much stronger opponenets. Kingdom consolidated is: good army, stability so I won't have internal conflicts, basically either my direct vassals all like me enough to not want to revolt, or they are to weak to revolt even if they would want to. Too weak compared to my personal levies strength.

In this video I took all of Moldavia, while making sure that the regions I take remain stable parts of my realm. I took Transylvania and a bit of Temes. The video didn't end when I wanted it to end, but there wasn't much I was about to do afterwards. In the final sequence I was showing it's important to have counties of your own religion and culture so that the local population won't revolt. For religion you send the priest, with culture you can't do anything but wait it out. They only thing I wanted to do in the video and didn't get to, was after I won the war in Bosnia and was finally at peace, to move the capital to Campulung, but I already explained in the previous video and this video how to do it and why I wanted to do it so it's not much lost.

You only need the first video with Mumu to learn how to play the game. The other 2 videos are just extras.

I know it's 1 hour and unedited, but it pretty much explains everything yo need to know to have a basic understanding of the game.

In the 2nd videos I explained a few things I forgot to mention in my Mumu video, they are useful but not essential. And in my 3rd video I continued after I got over the crysis & bad RNG from the 2nd video.

I was originally only planning on 2 videos but wanted to show how I actually get to the top rather than just say "ok, now I'm good and can conquer pretty much everyone around me" after the 2nd video.

Good luck!
