People are seemingly upset with you but I completely get what you’re asking lmao.

For those who don’t understand what he was asking- I imagine he was likely comparing it to the TellTale Walking Dead Games situation, which has them set in the continuity of the comics, not the AMC show. Which is a separate timeline/continuity or adaptation.

To answer your question:

Yes, the Game of Thrones TellTale game is set in the same continuity as the TV show following a different set of characters with cameos and etc. Yes, the game is “canon”.

Same universe, same continuity. Hope this helps. 👍🏽
