You should know that The Game Awards will be held on Thursday, December 6 at the Microsoft Theater in LA at 9PM (ET). You can vote for your favorites right now at TheGameAwards.com, via Twitter Direct Message, Facebook Messenger, Amazon Alexa, Google Assistant, and the official Game Awards Discord server.
All of that seems really odd and they did not specify how to do any of that, but there you are. I even tried to ask my Google Home "how do I vote for The Game Awards" and it had no idea.
You will be able to watch The Game Awards live on December 6 through YouTube, Twitch, Twitter, Facebook, Mixer, Steam TV, PlayStation 4, Xbox Live, IGN, GameSpot, Polygon, MLG, and Caffeine.tv. Believe it or not, there are actually even more places still not yet announced where you can watch it, especially if you live in China....
