“…Although there are many reasons for their success, including the vivid virtual worlds they can present and the interactions with other users that they foster, one key driver may be the falling prices and rising specifications of personal computers. Cheaper and more powerful hardware also means that 3D instructional tools are now used in an increasing number of fields, such as for enhancing spatial visualization skills in design education (Park, Kim, & Sohn, 2011), in 3D virtual learning environments (Benvenuti et al, 2010;Paraskeva, Mysirlaki, & Papagianni, 2010), and in many other educational domains, including digital game-based learning (DGBL).
