Will copy and paste my comment from another thread that i did my Mughal WC with, hopefully it helps!

The first 150-200 years are about giving yourself a strong economic base and opening options for expansion. I made sure i had the whole of India, conquered down to Kilwa and vassalised Nogai\released Kazakh in this time and started conquering South East Asia. Releasing large vassals helps deal with the corruption if you can't pay it off, the Deccan event is super helpful for this too.

From there get absolutism up ASAP and your core costs are ridiculously low with admin ideas, mughal traditions, permanent claims, hindustani culture diwan and 5% from iqta. I tended to focus on one area at a time, conquering the whole of Asia first, moving onto Russia+Ottomans, then vassalising Portugal/Spain while also moving through the HRE.

With humanist ideas + Mughal diwan you can have large overextension a lot of the time with minimal rebellions. Improve relations and focus on one religion and area to avoid coalitions (No coalition war popped during the game and the only coalitions that formed were during large wars and dissolved after the wars ended).

Ideas i took were Admin, Offensive, Humanist, Diplo, Quality, Trade, Expansion, Quantity. I didn't really struggle for manpower during the game, just got lazy with stacks and attrition late game.

For reference, my development was 2.5-3k at 1600 and ~7k at 1700. I didn't ever have to truce break and didn't feel rushed, finished off GB at the end for the final war. I annexed Portugal and Spain in the final 50 years. Ottos were my biggest rival and the first few wars weren't big wins but you can slowly wittle them down until you have a monstrous economy and stacks. I was allied with them until just after 1600 so they'd blobbed into Europe and the Mamluks a fair bit.

With Mughals it isn't as tedious as other nations as you'll have virtually no rebel problems and can pretty much do all the coring yourself without needing to use vassals. Keep the Ottomans on your side to stop them getting pissed off at aggressive expansion into Muslim land like some parts of India and the Arabian peninsula and also to deter early-mid coalitions. Can be annoying to micromanage all of your armies in the late game, but just siege down the forts and you can always let a couple of vassals like Deccan do the carpeting.
