The purpose of this study was to examine the various categories of games and the similarities of behavior in each category, based on data analysis of university students' self-evaluation of selected games. Data were collected by questionnaire and interview. The questionnaire was administered to 239 (111 male and 128 female) students and asked about their overall evaluation of each selected game, whereas the interview was conducted with 17 (7 male and 10 female) students to ascertain the reasons why they thought they would be suited to the selected games. Cluster analysis was conducted on the questionnaire data to clarify the game classification quantitatively, and qualitative analysis was conducted on the interview data to clarify the similarities of behavior in each game category. The results reconfirmed that the invasion, net, and striking/fielding categories of games were classified similarly to those in several previous studies. In addition, several similarities of behavior in the game categories were revealed.
