Tester: most important during the final stages of development, testers will try the game themselves and list anything bad or good about the current build. There will be two major types of testers, one is a blind tester, who will have no information regarding the development scene. They are meant to simulate how the end-user will interact with the game. The other type is the development testers, who will focus on the details that the developers have left out, or find any balancing issues that might happen during gameplay.
