This paper explores the attractiveness of Pokemon which is a turn-based Role Playing Game (RPG) and has been very popular for the decades. In this study we focus on Pokemon battle which is the most important component in Pokemon. The game refinement theory is used as a tool to assess the degree of sophistication of Pokemon battle. For this purpose we apply two approaches of game progress modeling to derive game refinement measure, i.e., score limit sports approach and board game approach. We calculated game refinement values for Pokemon battle by collecting many data from Pokemon Showdown, an online Pokemon battle simulator. The results show that the values of game refinement for Pokemon are slightly lower than the comfortable zone that we supposed in the previous study. We are tempted to conclude that such a slightly lower value is important to attract children with appropriate degree of excitement in playing Pokemon.
