Format
The 2013 StarCraft II World Championship Series introduced large scale changes after the inaugural 2012 StarCraft II World Championship Series, turning the World Championship Series into the highest level of StarCraft II competition and culminating in the Global Finals at BlizzCon. Based on the format of the Global StarCraft II League, three Premier Leagues were formed - Korea, Europe, and America. Each region also contained a Challenger League that fed into Premier, in reaction to Korean dominance across all WCS leagues. Korea's WCS Premier League returned to Global StarCraft II League branding, with all three seasons fully run by GOMTV, marking the end of the Ongamenet Starleague. All WCS leagues featured three seasons of regular play, with cross-regional Season Finals pitting the top-placing players of each region against each other.Non-WCS events which covered some prize pool, online coverage, and qualification requirements were allowed to become sanctioned events and give out WCS Points to count towards qualification and seeding in the Global Finals.
