eSports is one of the fastest growing—and most cutthroat—industries in the world. A confluence of technology, culture, and determination has made this possible. Players around the world compete for millions of dollars in prize money, and companies like Amazon, Coca Cola, and Intel have invested billions.

eSports events have sold out Los Angeles’s Staples Center, Seoul’s World Cup Stadium, and Seattle’s KeyArena. Hundreds of people have dedicated their lives to gaming, sacrificing their education, relationships, and even their bodies to compete, committing themselves with the same fervor of any professional athlete.

In Good Luck Have Fun, author Roland Li talks to some of the biggest names in the business and explores the players, companies, and games that have made it to the new major leagues.
