Giant stadiums, teenage millionaires, super fans, and addiction: Welcome to the world of eSports.
In the final part of "eSports," we join 40,000 screaming fans at the League of Legends world final—the highest-attended eSports match in history.
Superclubs and suicide: the darker side of eSports.
We meet KSI, the UK's ultimate gamer celebrity, and follow Team FNATIC to Gamescom—the biggest gaming event in the world—where they battle it out for Europe's top eSports title.
We get a crash course from a professional gaming commentator, take a trip to gaming rehab, and try on character costumes at the HQ of South Korea's best cosplay team.
