Game simulation design and development require instructional designers and game/simulation developers to collaborate. Instructional designers are not typically trained in game or simulation design and development. Designing and developing a simulation or game is not the same as designing and developing for an elearning course. Although there are similar concepts, there is one glaring difference – simulations are three-dimensional environments. It is this element that instructional designers do not have any experience. Creating a Flash animation in an elearning course is not the same as creating a three-dimensional world, where characters must interact, objects manipulated and how the player moves through and interacts with this environment. The result of not understanding 3D simulation design/development is cost overruns, staffing issues, and production delays that result in missing critical milestones.
