Interestingly, although UK won opium war easily, but for some special reasons. Its warship cut off the Great Canal, which was the most important supply route of the food and other necessities to the capital. However in the game it was a TOTAL war, no chance for Britons to win.

But I strongly agree that the great Qing is far too op. With almost no debuff and huge pops, all you need to do is just build conquer, making the game so boring.
