This is Benjamin. He has a kidney disease called nephropathy, and he really wanted to see a professional StarCraft II e-sports match in South Korea. Blizzard, through the Make A Wish Foundation, made that happen.
Benjamin and two friends were able to go to South Korea, play against his favorite SCII team, Prime, and attend the Global StarCraft II League finals.
This isn't Blizzard's first teaming with the Make a Wish Foundation. The game company has made wishes come true in the past and raised money for the organization by offering "charity pets", such as a Pandaren Monk and a Moonkin Hatchling pet.
