Formalizing casual games: A study based on game designers' professional knowledge

While the casual game market is expanding, there are increasingly few research projects and explorations about the definition of this game style. Existing definitions are contradictory and some areas, like casual game design practice, remain under-explored. Using game designers’ professional knowledge, this study aims to provide a new understanding and perspective towards definitions of casual games. Results contradict previous studies that have advocated for a radical shift in casual game design values. Outcomes indicate that certain traditional concepts like challenge are still valuable in understanding casual games. The discussion illustrates how different traditional concepts fit with the casual game trend and how some recent assertions about casual game definitions might be deceptive for game designers.
