As far as I’m aware, this is the best endpoint to find game information: https://api.twitch.tv/kraken/games/top
I can see only channels and viewers, but not followers.
Dont expect things to be added to kraken anymore beacause its deprecated.
But maybe it will be added to helix if you ask them nicely 
Hey twitchies, can you please please add game followers, channels and viewers to helix games/top endpoint?
Hey, thank you for the feedback 
We’ll discuss this as we continue to develop the Twitch API. Thanks!
