Then we use testers to both play new games and critique them so that they are fine-tuned to be exactly right before hitting store shelves. It's like having a child. You watch a game go from being just an idea on paper to an actual product being shipped. You discuss the basic idea for the game, evaluate what needs to be done to do the job properly, then hire the best people for that job and give them the resources they need to turn out an excellent product. Our newer games can involve the extensive filming of people and stars to capture as wide a range of realistic motions and expressions as possible.
Some games are almost like movies in themselves.
Sometimes I have to act as a babysitter and a diplomat when trying to reconcile different people with different personalities. The reality is that testing often means playing just ONE level of a game hundreds of times without ever getting to play any others until the finished game ships. Although I studied electronics in school, I had no formal training for the position I'm in now.
