"John Carmack's Triumphant Return to QuakeCon After a Decade: A Joyful Homecoming"

John Carmack, co-founder of Id Software, returned to QuakeCon for the first time in a decade, expressing his happiness at being welcomed back. Carmack had been involved in legal battles with his former employer, Zenimax Media, after leaving Id Software in 2013. He later became the center of a lawsuit between Zenimax and Oculus parent Facebook, which he was eventually absolved of. Carmack sued Zenimax in 2017, but an agreement was reached in 2018. Carmack's return to QuakeCon has sparked speculation about a potential collaboration with Microsoft, following their acquisition of Zenimax.
