Add the ability to "Follow" a game
Follow a game to see all updates relating to that specific game.
As an addendum to this it would be great to have some type of functionality to see who is playing a game at a specific time. For instance if I was currently playing Far Cry 3 and followed its activity I could find others playing the game and maybe organize some type of multi-play. This would probably also be good for more involved games like Dota2 where people are constantly looking for coaching.
