Played as Mughal Empire
Played as the Mughal Empire by changing the setting.
The Mughal Empire is crumbling it is quite true. There are only a few provinces that have roads and many buildings are undeveloped. Moreover the Mughal Empire has no six building slot cities, so no naval research can be done. And the Maratha confederacy is already at war. However the Mughals have the largest treasury and trade partners number is the highest jointly (with the Ottoman Empire). The army is weak and scattered. No starting technology.
Above all the most of the ministers are worthless and producing negative buffs for the Empire. People are very restless all over the Empire.
So as the first step the emperor Aurangzeb reshuffled his cabinet. Fortunately there were able candidates for each minister he removed and after the reshuffling, the unrest was settled immediately.
The next step is diplomacy. The Maratha confederacy is offered money for the peace, trade agreement and alliance. They counter demanded the whole money of the entire Mughal treasury. It was agreed, and then the whole money of the Maratha treasury was squeezed back by selling the military access. The same was done to Mysore and Persia, and their treasury was also squeezed. However the Portuguese and the Dutch were smart enough to refuse the offer. After completing the diplomatic actions, Mysore and Persia are the allies of the Mughal Empire and the Marathas are the new trade partners. The huge money (35000-36000 gold) was utilised for purchasing the starting technologies from the Prussians and the Ottoman Empire. The new trade relations were established with the 13 colonies, new Spain and Louisiana.
After that the Mughals concentrated on developing the economy, military and infrastructure, until they started expeditions.
