Quoted from o-din:(sure, GOT and TWD are recent , but neither game is that new any more and neither are the shows.)
So long as they are producing new content/episodes for the shows, I'd say the shows are current and new as they possibly could be. Both games are still in production at Stern as well.
I wouldn't want a game based off of a show that was only one season. What if it has a huge quality reduction in season 2 like Helix did?
