My wife wanted me to play it so she could find out what happens next too. I had never watched the TV series but once I completed the game, I bought series one on bluray, watches it all in a day & then sold it again for £2 more than I bought it for. Got series 2 yesterday & watched 6 episodes already
Really looking forward to the next episodes/series but I might wait until they're all available first so I can keep playing through rather than waiting to find out what happens after each one
