As educational games become more pervasive, the evolution of game design software is inevitable. This study looked at student perceptions of teacher created Serious Educational Games as part of a project striving to create a game development software where teachers and students create games as part of educational activities. The objective was to use evidence from student perceptions to inform further development of the software. A mixed method design ascertained data from 181 male and 178 females from 33 teacher created games. Results indicate that the software is relatively effective by the supporting documentation and training lacked in several areas. This information led to the creation of a commercial game development software set for release in 2010.
