His only interaction with his biological father was on his 13th birthday, a meeting which turned violent as McGee's father drunkenly assaulted him that night.

According to former id staff Sandy Petersen, Tim Willits was the one responsible for McGee's firing (although he did not mention Willits by name; referring to him only by "Snake" and "X"). Allegedly, during the development of Quake II, Willits deliberately gave bad level design advice to McGee and when he presented his work to Carmack, it angered him and McGee was fired soon after. McGee has stated to this day, he still has no idea why he was fired but acknowledged the fact that it was due to "internal politics and my own failings"
