Programmer Christopher Green has had a long career in the games industry, with a development history that included Amiga’s Flight Simulators, Ultima Underworld, and Magic: The Gathering Online before ultimately working at and retiring from Valve—twice. Green had previously made a six-year attempt at retirement starting in 2017, but returned to Valve for another go in 2023.
Earlier this week, Green announced on his blog that he’s once again had the “epiphany” that he “might actually enjoy some of those things that I hear retired people do,” and is giving the whole end-of-career thing another go—for keeps this time. To mark the occasion, Green hosted a pair of AMAs on Reddit to share some of his thoughts on 45 years in game dev and a Valve tenure stretching all the way back to Half-Life 2.
Answering one redditor’s question about what it was like to witness some of Valve’s earliest years, Green said leaving his previous job in 2004 “was a huge transition”—particularly because Valve’s finances were looking somewhat grim at the time. Previously, he’d worked at independent developer Leaping Lizard Software, where he did the initial rules and card coding for Magic The Gathering Online—something he elsewhere called his dream project, as he remains an MTG fan to this day.
“I had some misgivings at first as Valve was losing money finishing HL2 while my company that I left was profitable and MTGO was generating more revenue than Valve,” Green said. “But things got better really quickly.”
