Street Fighter is the largest fighting franchise and has had huge success with its latest console release Street Fighter 5 (SFV). As an eSport, it is played one versus one where the players choose between different characters. A lot of the old characters like Blanca, Chung Li and Dhalsim are still available. The game is usually played on console but is also available as an arcade game.
There are several big event circuits available for SFV where CapCom Pro Tour is one of the largest. It's especially fun to see that they have stopped all around the world with a focus on Asia, North America and Europe.
