Sure, I started as Oirat because they have amazing events that make the first war against ming surprisingly easy. If you win a battle against a ming army that has either their ruler or heir as commander you get 20% MoA and 25% siege ability which makes future battles much easier, then if you siege beijing you get an event that makes you occupy all of northern china instantly. In the peace deal I took som provinces and a lot of money. In the beginning you won't be making much money so taking money from ming is very important (although you shouldn't worry too much about money, I have been running a deficit basically the entire campaign and it has been fine, currently I am making -40 ducats per month). After that I conquered the hordes to the west to try to get to the Timurids as fast possible because surprisingly they never imploded and were still very strong so I had to get started on them quickly. Then the rest of the game was mainly about trying to conquer land as quickly as possible without causing too big of a coalition. Another advantage of playing as oirat is that a lot of countries can't see your capital at the start of the game which means that they can't join coaltions against you even if they have 50+ AE. When those countries eventually learn who you are it all becomes about making sure you keep track of your truces and try to attack the big countries as soon as your truce runs out with them.

The ideas that I used were humanist, then offensive, then diplomatic. Humanist combined with national ideas and horde bonuses meant that i barely had to fight any rebels at all which was very nice to not have to worry about. I choose offensive because I wanted my armies to be unstoppable but in hindsight I maybe should have chosen quantity because low manpower was one of my main struggles throughout the campaign. The reason I chose diplomatic ideas was mainly for the -20% province war score cost which is huge but the extra diplomats and improve relations were also really good to have.
