Kit Harington has made a notable return to the Game of Thrones universe by starring in an advertisement for Zynga's new mobile game, Game of Thrones: Legends. In the ad, he embodies his iconic character Jon Snow, delivering the famous line 'Winter is coming' as he navigates a bar filled with references to the series, including nods to Targaryens and White Walkers. Harington expresses excitement about the game, stating it serves as a tribute to the fans of the franchise. The game incorporates characters from both Game of Thrones and its spin-off, House of the Dragon, allowing players to lead their own house to victory through various missions and challenges. Despite the enthusiasm surrounding the game, some fans feel a sense of disappointment regarding the canceled Jon Snow spinoff series, which had initially generated much anticipation. This advertisement marks Harington's first involvement with the franchise since the show concluded in 2019, highlighting how the series' legacy continues to resonate in popular culture.
