It was Dark Souls 2 but yeah, it was kinda hilarious, since it was basically the first time we ever heard directly from him or got an "official" selfie in almost a decade of him making music, and it was just to say "I'm not sure if I will have many new tunes for a while because I need to play that game a lot", even though he already had the reputation of not putting anything out for long stretches of time. It was so bizarre.
For reference, it's the guy in the black hoodie on the right side for the first third or so. Also his song plays at around 6m in, and you can see him rolling a join a bit later, hah.
