Scenario Designers

From AgeofWiki

Scenario Designer is basically a person who designs scenarios (see Scenario Design for games). Professional designers work for the game development companies. In this Age of Wiki you will find most of the time Fan designers. Fan designers are people who design scenarios in the scenario editors which come with the games. They do this in their free time and with non commercial intensions.

Usually a designer creates the map with elevations and terrains, places the objects like for example units and buildings and creates the triggers which give the scenario its activity/ interactivity.
