Aye, 'twas a really awesome game, I still play it. Though personally StarCraft is still my favourite. ^^
But I did learn about Hyderabad from EUIII, whereafter I looked it up on Wikipedia. Thanks to that, the idea of independent Deccan states was born in my mind and Hyderabad is but one of them, along with Goa, Travancore, Mysore and Tamil Nadu.
