This chapter intends to present game designers’ perspectives which elaborates on the ways they approach designing games. While it is diverse, the interpretive analysis of 17 game designers’ perspectives will be able to shed light on how game-designing processes may be influenced by their experience-based and reflective practice, or whether they apply formal methods based on how game-designing fields represent. Furthermore, it discusses whether the formal methods explained by the game designers resonate with existing literature and compare the relevance between the practices and the literature that advocates best practices. The results are discussed through interpretivism paradigm, to provide the essence of game designers’ experiences and approaches. Lastly, it concludes with a list of common practices in their designing processes for games and a future direction towards how we can understand game designers’ perspectives and ease the designing process of games.
