The Dragon and the Pearl is, essentially, the Britannia game concept set in China during the same era. The succession of invading hordes arrive historically accurately, but points are rewarded for surviving rather than being in the right place at the right time, so strange and interesting results are possible. A full historical background is provided so you can try to get it right if you want to, the dice-based combat system has a fair element of chance to stop it getting too serious. - BoardGameGeek
