He had previously tried to leave Gabe Newell’s company, but ended up taking another job, though that’s now over.

Programmer Christopher Green has had a long career in the gaming industry. During his time as a developer, he worked on titles such as the Amiga Flight Simulators, Ultima Underworld, and Magic: The Gathering Online, before finally joining Valve. He retired from Valve twice. Green tried retirement for the first time in 2017 and returned to Valve in 2023. Earlier this week, Green announced that he realized he might enjoy the things retirees do, so he’s trying to retire for good this time. To mark the occasion, Green held two Ask Me Anything (AMA) sessions on Reddit to share his thoughts on his 45 years in game development and his time at Valve, dating back to Half-Life 2.

Green said that leaving his previous job in 2004 was a huge transition, especially since Valve’s financial situation seemed bleak at the time. He had worked at Leaping Lizard Software, where he developed the initial rules and card coding for Magic: The Gathering Online. He called this project his “dream project” and remains an MTG fan to this day. Initially, he was hesitant because Valve was operating at a loss while finishing Half-Life 2. In contrast, the company he left was profitable, and MTGO generated more revenue than Valve. However, things quickly took a turn for the better.

According to Green, he worked on numerous projects during his 16 years at Valve, including both Source engines, Day of Defeat: Source, The Orange Box, the two Portal games, and many others. This meant attending hundreds of meetings with Valve’s co-founder and president, Gabe Newell. Green described Newell as having a somewhat inscrutable personality. However, it’s clear that Valve’s legendary self-directed work culture, in which employees are seemingly free to work on projects of their own interest and discretion, may not be as self-directed as Valve’s own employee handbook suggests. When asked whether Valve employees are truly free to work on their own projects as long as they don’t conflict with the studio’s other work, Green replied that this is only partially true.

According to Green, new employees face serious resistance if what they want to work on is too far removed from reality. At least one popular, successful game mode was created in secrecy by a programmer who was the only one who believed in it. Green revealed that this game mode is none other than the popular HL2DM. This isn’t the first time we’ve heard that Valve’s flat organizational structure can cause problems. In 2023, People Make Games published a report featuring interviews with current and former studio employees who claimed that the organizational structure could distort workplace dynamics and reinforce the lack of diversity at Valve.

This is Green’s second departure from Valve, so he is once again giving up his employee perk of having full access to all Steam games. However, based on his description, it seems he’ll continue to work in comfortable conditions. His home office features a 100 GB Ethernet cluster with over 512 cores, plenty of GPUs, a large-format art printer, and a substantial collection of electronic and mechanical tools. He has many ideas for projects he’d like to work on and people he can collaborate with. However, these projects are more likely to appear on GitHub or in personal one-offs than in commercial games.
