Fortnite

Fortnite is a game hosted on 4Chan that The Doctah was required to play in order to resuce Tim. He got a victory royale, and, for a short time, had more Fortnite wins than the Mastah. The Doctah was flagged as cheating due to his use of the TARDIS in-game, and got banned after rescuing Tim. Because of the Mastah’s anger over the Doctah having more wins than he had, he proceeded to attempt to watch every piece of Fortnite content and become level 100 in the battle pass in 20 seasons of the game. As Fortnite in real life approaches 20 seasons (currently 18), one can roughly estimate the range of the time travel.
