League of Legends, you'll want to mark your calendar for August 3rd. Major League Gaming is hosting a three-day event that features four of the planet's best teams.
The stakes are pretty high too, as the first-place team will take home a $10,000 prize. All of the tournament matches will be streamed via MLG's website, which means you can watch over 20 hours' worth of pro LoL gameplay for free. You can also upgrade to a 1080p hi-def stream and get full DVR functionality if you like.
The tourney concludes on August 5th, and you'll find a full broadcast schedule as well as all the event details at the Major League Gaming site.
