My guess is blizzard. Maybe Riot. Blizzard hasnt really done modding communities before, but maybe they are starting to see the appeal of it? Especially with their heroes of the storm game Besides that, ya, could definitely be riot.
I really can't wait! What is this massive studio? I as some others are guessing it's Blizzard but Blizzardfest is already is a thing who else could it be?
Possibilities: If Riot: Community skins for LoL If Valve: Another Dota contest?(highly unlikely) If Blizzard: Assets for WoW expansion/Community skins for Heroes of the Storm or….. the long awaited Penis Tank Contest?
wishing they would announce it at some point today since this is a 3 day weekend for us in America. Makes me think with the title as "world's biggest video game" that it would be Riot or Blizzard, unless by biggest they mean game size, maybe (as opposed to player base?) Excited to see what gets put out there.
