The world, its cities, regions and its people are well thought out and richly designed and described. The trading system works well, and is a challenging but fun aspect of the game to master, and complemented well by various other tasks and mechanisms. The (current) lack of a central, over-arching questline, and the fact that there is no way to play the game perfectly (choosing one thing generally puts the second option beyond your reach), means that you, as a player, are both free to do as you want and that choices are meaningful. Truly meaningful, not some small changes to a reward or dialogue. I'm interested to see how the game will be further developed.
