Fig. 6 shows the average time students spent in playing games. The analysis shows that 60% of students play games between one to three hours, 30% play less than one hour, and 10% play more than six hours. Majority of students play games between one to three hours. Time spent in lectures or labs are in the range of one to three hours as well. Therefore, 310 using games to learn object-oriented seems to be a good approach.
