Settlers IV is graphically indeed different from Settlers III but not necessarily better. The stability of the game remains over its predecessor on the route and some things do not work either. So it can be played as a cooperative game against the AI (Artificial Intelligence), for example, in Settlers IV no party in the LAN (local area network), because errors occur after a short time, which eventually bring the game to crash. So you have to assume that the co-op in this game is not working properly. I turned with this problem already at the Bluebyte team. Here, it was confirmed to me that is no longer working on the game. Additional patches are no longer to be expected and you have to take with the purchase of this product probably some disadvantages. Therefore only 2 stars!
