Kaulbach, Ubisoft's International brand manager, stated: In an interview with Eurogamer.de, the game's writer and co-designer, Kathleen Kunze, said of the decision to split the franchise: "That was the decision of the fans. There are those who say, "We want to continue with the old Settlers concept". They have great fun playing the original Settlers II. And then we have the people who always want innovation. The fanbase has, more or less, developed this way. Because of this, however, there was a lot of disunity in the community, so we decided to label things as "Traditional" and "Evolutionary"". Although part of the Traditional strand, Aufbruch der Kulturen does feature some new game mechanics. For example, the different races are no longer merely aesthetically differentiated, but now have different economic models, different buildings and different soldiers. The Egyptians' economy is very basic, with no complex daisy-chain economic processes, and it can produce large numbers of soldiers very quickly, although these soldiers are comparatively weak. In contrast, the Scots' economy is more complex, with more multi-stage processes, and takes longer to recruit an army. Scottish soldiers, however, are very strong. The Bavarian's economy and soldier recruitment falls in the middle. The game also features magic, whereby each race can call upon their respective deity for economic and/or military assistance. Certain economic process have also been expanded. For example, in The Settlers II and 10th Anniversary, a baker needs flour and water to make bread. In Aufbruch der Kulturen, however, a baker needs flour, water, and salt, which must be mined. Also new is the sacrificial temple; if the player places a certain amount of resources on the altar, the settlement will receive a bonus for a limited time, such as buildings moving into areas unreachable by enemies, soldiers receiving an attack bonus, or goods produced faster. Another change is that the game no longer features individual tools; instead, there is simply a single master tool which all workers use in their respective occupation. Single-player games also feature an adjustable difficulty level. In the game's single-player campaign, during the preparation period for the Olympic Games, the god Olympus notices that the people of the world have become obsessed with money, waging wars on one another to acquire more and more land, and laying waste to the earth in the process. Disgusted by their behaviour, Olympus decides to cancel the games. Meanwhile, the angels
