The Olympic Games are also seen as a potential method to legitimize esports. A summit held by the International Olympic Committee (IOC) in October 2017 acknowledged the growing popularity of esports, concluding that "Competitive 'esports' could be considered as a sporting activity, and the players involved prepare and train with an intensity which may be comparable to athletes in traditional sports" but would require any games used for the Olympics fitting "with the rules and regulations of the Olympic movement". Another article by Andy Stout suggests that 106 million people viewed the 2017 Worlds Esports competition. International Olympic Committee (IOC) president Thomas Bach has noted that the IOC is troubled by violent games and the lack of a global sanctioning body for esports. Bach acknowledged that many Olympic sports bore out from actual violent combat, but stated that "sport is the civilized expression about this. If you have egames where it’s about killing somebody, this cannot be brought into line with our Olympic values." Due to that, it was suggested that the IOC would approve more of esports centered around games that simulate real sports, such as the "NBA 2K" or "FIFA" series.
