Formany, words like "MOBA" and "Dota 2" might sound more like random collections of letters than a massively popular gaming genre and game, respectively. Valve, Dota 2'sdeveloper,wants to educate the masses by putting the game and atrio of its international players under the microscope in FreetoPlay.Onemight find Valve's efforts feel a tad self-serving when compared to, say, Indie Game: The Movie, but,basedon the trailer, the documentaryseems more like a look at the human side of professional gaming than it does an advertising puff piece. If checking the film out and sitting in on a Q-and-A session with its creators sounds like a good time, tickets to next month's San Francisco premiere are $25 through Eventbrite.
