In recent years, a major boom in the initial stages of Software Engineering has been experienced, mainly in the achievement of the definition of the Requirements and Objectives Models of the problem to solve. This paper focuses on the field, making a proposal that actively involves the client in the development process and partially automates the way how requirements are elicited. In this case, the tool provides an initial approach to the models of the system in an automated way. The tool provides the models according to INGENIAS methodology, but it is adaptable to other methodologies or production environments which have a characterization based on similar principles.

Multimedia systems, and in particular games, have special characteristics that make the process of obtaining system requirements very difficult. In most cases, an important work of codification is needed in order to obtain a prototype that can be analyzed by the customer and make requirements elicitation easier. This paper proposes a way of facilitating the process and obtaining a prototype in a short development time. Our proposal is based in the combined use of a well-known methodology for the construction of Multimedia Systems and Alice, and follows an Agent Oriented Software Engineering approach. The work introduces the process proposed as well as a tool that provides support for such process. Besides, a case study shows the application of the process and the tool to a simple example. From this example, the suitability of Agent Oriented Software Engineering approach and the proposed process for game prototype development is concluded.
