"Once the technical and artistic vision of the game is planned, people can be brought onboard to start the main production work on the game. Artists build the environments, characters, and objects for the game world, and designers write the dialog and start making things function story-wise. The most difficult part of this stage is that everyone is working with partially complete technology, since the game programmers are also working to create the functionality of the engine and game systems. It's a careful sequencing of work that allows us to complete this stage, similar to trying to film a movie while technicians are still building your lights and cameras. Once the bulk of the work on the game is complete, the bug database starts to take over as the driving force in development. The list of remaining tasks starts to dwindle, and the team works through the enormous task of perfecting the millions of details that will make it a solid game. Quality assurance testers also take center stage, providing valuable feedback about what's fun and what's not, in addition to spotting bugs. Designers work throughout this phase to improve the balancing of the game, making it more fun and exciting with every day."
