The festival atmosphere would return for 2015. In StarCraft, the event served as a redemption arc for Joo "Zest" Sung-wook. The Korean had failed to qualify for GSL (Global StarCraft League) 2015 Season One, losing two series as a heavy favourite and drawing accusations of a ‘slump’. At Katowice, Zest’s victory silenced those discussions, taking home the lion’s share of the $117,707 prize pool in the process.
In CS:GO, there was less romance; the theme was one of brutality. Fnatic, the best team in the world, demonstrated their dominance and swept past both NIP and VP – the two finalists in 2014 - to win the second Valve Major at Katowice. The Major was run at the same time as an all-female CS:GO tournament, ‘IEM Challenge’. With a $30,000 prize pool, winners Bad Monkey Gaming would take home more than double their previously largest prize purse, professionalising women’s esports and starting the journey that led to #GGFORALL – ESL’s brand new Global Women’s circuit sponsored by Intel.
By 2015, IEM Katowice was one of few international League of Legends tournaments outside of Riot’s direct control, meaning there were fewer and fewer opportunities for regions to challenge the pre-eminence of South Korea, the tiny Asian peninsula that had dominated League of Legends from 2013-15. Gambit Gaming, in Katowice in 2013, were the last Western team to win an international tournament; a North American team had not won any event with Koreans present for four years.
That would all change in Katowice, with the “biggest upset” in League of Legends history. GE Tigers were undefeated at the top of Korea’s LCK; their opponents, World Elite, were 14th in the Chinese equivalent. Against all the odds, World Elite would triumph against the favourite for the title, reaching the final against TSM. The level of this upset was made even more obvious by the final: Team SoloMid, aided by an MVP performance from Søren "Bjergsen" Bjerg, would decimate World Elite 3-0. Katowice had once again hosted something special - the planting of the Stars and Stripes on a landscape cluttered with Taegukgi.
