How do you play eSports?
eSports are not played between friends who like gaming, but between well-drilled teams in big stadiums set up with screens so thousands can watch the games. Just like in football, teams are passionately supported.
What video games are played?
League of Legends, Defence of the Ancients 2, Call of Duty: Black Ops 2, Starcraft II are just a few.
