The document discusses reasons for applying AI research to games. It notes that games are fun, provide an accessible industry with real problems to solve, and allow for easy science popularization through their accessibility. Games also offer a more convenient testbed than robotics with fewer hardware requirements and lower costs. Competitions in games can help identify expert AI, and games provide a huge accessible collection of match and usage data for analysis without confidentiality issues. Games also serve as an excellent environment for studying human-machine interaction at scale through cooperative and competitive play. Finally, games provide a simplified world that is rich enough to pose scientifically relevant problems while having clearer rules and metrics for success than the real world.
