A Game Designer is an individual who designs the structure of a game including how it will be played and what the rules will be. He or she may create one or more of many types of games, including tabletop games, card games, and board games, but the most common type currently developed are video games. Over the years, as video games have gained popularity, game designing is dominated by complex games played on computers, electronic devices, and other gaming consoles. Video gaming has evolved into a substantial industry. Individuals who are interested in becoming a game designer should have a passion for games, both digital and nondigital. Game designing requires the ability to come up with new ideas and concepts, and the ambition to make something enjoyable and fun. People who do this job need the capacity to think in the abstract and be multidimensional. Video Game Designers are typically members of a gaming company's product development team, which may consist of artists, storyboard writers and lead designers. Game designers are most heavily involved in the enhancing the aesthetics of video games or how they look and feel to the consumer. The responsibilities of designers may vary. They troubleshoot for bugs and other problems within the design of gaming systems, develop intricate features (such as game-play control, multiplayer and user interface), conduct collisions tests to improve graphic content and carry out rigorous quality assessments.
