Want to keep track of your favorite games being played on Twitch? That's now possible with a new update.
You could already follow your favorite channels on Twitch, but now you can follow specific games as well.
Just search for a game you like using the already existing Games search, then click on the Follow button at the top of the results for your game(s) of choice (in the above screenshot you can see I am already following Mario Kart 8).
The official Twitch Blog entry about this feature is here.
