The rule for the game "Realm of the Desert Sons" will officially be changed as follows:

Previous rule: When a tile is aligned with the border of the game area, it can be done either with its desert side or its oasis side.
New rule: When a tile is aligned with the border of the game area, it can be done only with its desert side.

Klaus Teuber explains this rule change as follows: "The main focus of the game is on using the different heights of the influence stones for tactical purposes when jointly discovering oases. Unfortunately, it became evident that many players used the previous rule to act alone, moving their caravan along the border of the game area. As a result, caravans are rarely discovered jointly, and the different heights of the influence stones are almost irrelevant. This turns "Realm of the Desert Sons" into a not very interactive game that highly depends on luck. This new rule steers the game into a direction I experienced when developing the game, and which I as the author had in mind."
