Macera Tuneli is a free style game which will be used for education of disabled and preschool-age children. The scenario of it will be as free (dependent to choice of the user) as possible so that the user will not be bored and will play it for a long period of time. Thinking of the fact that target audiences are children, freestyle comprehension becomes such important. One might be able to create a new scenario for each use since different features of the tool might be used in each time for different cases. Maximized freestyle will diminish Macera Tuneli from its competitors. Macera Tuneli will be developed on Unity in order to make it compatible for different platforms. It is considered that this compatibility will increase demand for the game. Since it will reach more users with good features, it will surpass the competitors once again. Moreover, Macera Tuneli will allow user to record its activities, which indicates to another serious problem. Today, it is not that common to record activities, which are may seen as results for disabled children, in a game so that it is not really possible to analyse capacity and improvement of a child. Recording ability of the game will score another goal against the competitors and make the game reach its purpose more. Macera Tuneli will be developed in cooperation with Prof. Dr. Kursat Cagiltay and his team. It will support his game project for disabled children and take it one step further. Thus, distribution policy will be determined by them. It would not be true to state whether the game will be free or be offered for sale, whether it will be sent to the schools or also provided in the market or not.
