I had a lot of fun playing Bengal, aiming for the Bengal Tiger achievement.
They have a decent starting position and you do not need to take very much in order to form Hindustan. Doing so gives you an absolute massive amount of permanent claims, and with that you can wage war literally as fast as your manpower, rebel chance, aggressive expansion, etc. will allow you. I was able to very rapidly gain land as I was allied to at least one other major power there so the AE they gained was much less and kept them from getting ticked off, which meant I could also easily betray and backstab them later.
From there it was pretty easy to hit the shattered Timurids + the other hordes who had been taking land from them in order to get the objective.
Alongside that, I was colony hopping to reach South America, which allowed me to westernize.
After catching up, I used colonial expansion to face off against England, taking over London as well as stealing a lot of their colonies. By leapfrogging to Canada, stealing more colonies there, colonizing a bit of it on my own, colonizing Taiwan and using that as an invasion point to take Canton, I also got the "Sun never Sets" achievement.
