Just to note that the rough cut of the Takla Makan desert landed today, and I will thus be starting work on the fourth and final region of the game. I've already done the historical work, and have a list of all the settlements (the Han Empire kept such great records!), and Buddhist shrines for the region, but they all need placing.
Meanwhile, terrain sprite production continues apace, and the Save Game is what our programmer is working towards right now. The last Alpha build should land in the next couple of weeks, fingers crossed.
