The Game Awards 2014 will be shown LIVE tonight at 9PM (ET; 6PM PT). There will be live performances of songs from select titles, awards given out to your favorite games from 2014, and a number of all-new trailers for upcoming games!
You can watch it through Twitch (embedded above), or through: Steam (has a sale going on for many of the nominees), YouTube, Xbox Live, PlayStation Network, Wii U, IGN, Polygon, GameSpot, Kotaku, MLG, or Niconico. What I'm really trying to say here is that there are a ton of places you'll be able to watch this, provided you have an Internet connection.
I'm sure we'll have many of the new trailers up as news after the show airs tonight. Hopefully there will be some awesome surprises revealed.
