Coverage of the Starcraft 2 World Championships' European league has already begun, but the American league will start reportin' for duty at 4 p.m. EST. Day 4 of The International's main event continues at 3 p.m. EST, which can be viewed here or live in Dota 2. The Pokémon World Championships for video game finalists start at 8 p.m. EST, with the trading card game finalists following at 10:30 p.m. EST. You can watch both here.
If you're more into watching people raise money for charity rather than for themselves, the Triple Speed Runners are launching a week-long Zelda Marathon at 7 p.m. EST. The marathon will follow the timeline of the Zelda series rather than the order of each game's release, starting with The Legend of Zelda: Skyward Sword. Prizes can be won by watching the stream, but 100% of donations will go to Child's Play Charity.
