While participatory design (PD) has always been used in the context of community-based design, its application in designing primary school educational games is quite unique and requires total participation from children. Before applying PD in primary schools for game design, there are processes that must be identified. The selection of journal articles and papers are based on rigorous systematic literature review method, with 386 papers and books on participatory design and educational game topic identified, in which 21 were deemed relevant. An analysis table was developed on these selected papers to uncover the series of process and stages applied in the studies. Our analysis reveals that while different fields applies the participatory design process; most of the research share the same theme in the process. Meta analysis technique was used to form a suitable PD process framework from the theme gathered in the analysis. The formed is called the PDEduGame Process Conceptual Framework, which will act as a guide to educational game design. We suggest that the PDEduGame to be used in the context of primary schools in Malaysia.
