Naxy
From Tardis Wiki, the free Doctor Who reference
Naxy was a game similar to hockey played on the planet Cray. It originated simply as a sport but the game and its teams' supporters grew so violent that the objective became killing as many people as possible on the opposing team. In the past, there were many Naxy teams, but through the bloody complete their numbers were reduced to just two, the Gora and the Lineen. The Fifth Doctor came to Cray, hoping to witness Lord Darzil Carlisle broker peace on the planet. Not realising that Naxy was the war on itself, the Doctor agreed to join the Gora in a game of Naxy against the Lineen and ended up winning the game. (AUDIO: The Game)
