The competition found at the Dota 2 International was fierce, but Na'Vi was able to pull through and take the top spot, in addition to $1 million in prize money. (Big money, big prizes -- I love it!)
Sadly, I didn't get to watch as much of The International live as I would have liked. The streaming times were not conducive to me getting a healthy amount of sleep. The good news, however, is that you can catch up on the action through a series of videos Valve has posted on the Dota 2 website.
Another International is set for next year; the specific date and location will be revealed at a later time.
