There are several game designers types today. But before speaking about game designers types it is necessary to define the activities that game designers perform. Game designers are engaged in creating the content, rules and background of this or that game. Professional game designers have different specializations. For example, among game designers types are video or computer game designers as well as traditional or board game designers. But there are some certain principles of the game design process which is common for all game designers types. The first thing any game designer does is creating the concept of the game. The concept can be either created by the designer himself or borrowed from another designer. This is the way the initial design is developed. It also requires approval. And only then the production of the game may start. But it is quite possible that a number of problems can occur at this initial stage. The process of approval may take rather a long time. It can last for weeks, months and sometimes years. The project offered by the designer can be rejected. In this case the designer has to find the reason why the project of the game was rejected and to try to change it in order to appease the stakeholders. It happens that a design can never be approved. In this case the designer has to invent a new idea. When the design is finally approved, still a lot has to be done. A lot of people are supposed to work at the approved design of the game. They are producers, programmers and artists. The artists evolve the concept and the programmers try to develop different variants of the game to test different concepts of the game. It is the duty of the designer to document the whole process. The process of early production can be rather challenging for the designers. During the game development a lot of discoveries can be made. All the discoveries are to be documented. The design of the game can be represented as the living document, while the designer as the blood and the heart of the given document. It may be not easy to deal with all the changes, so the designer should be good at tracking and prioritizing the changes. It is also the task of the designer to inform the programmers of all the changes that take place in the process. A word processor is considered to be the main weapon of any designer. Thanks to the application, the design of the game grows from a few pages to volumes, indexed and cross-referenced. The content is made up by tables, graphs and different samples of artwork. But it is the text generated by the designer that makes up the most part of the text. It is of paramount importance that the game designer should be diplomatic. Traditionally there are lot of discussions and suggestions on this or that point of the game design. In this case it is the designer who should choose the best-fitting ideas. He should be rather diplomatic to announce the decision not to offend those whose suggestions were not used. The success of any work is provided by the team of specialists.
