“Ex-Valve Developer Shares Why AI Can’t Create Team Fortress 2 – A Must-See!”

It’s no surprise that a system designed to replicate existing ideas might struggle to create something genuinely original. When a renowned game developer claims that a genre-defining title could never be crafted by artificial intelligence, it’s definitely worth listening in.

For those in the PC gaming scene, Chet Faliszek is a familiar name, known for his pivotal role in writing for iconic Valve titles like Left 4 Dead and Half-Life. After departing from Valve in 2017, he has since become a vibrant presence on TikTok. In a recent video, a fan prompted him to consider any game design choices that might have been different if someone at Valve had called in sick. His response turned into a deep dive into the limitations of AI, shedding light on the development of a groundbreaking video game.

Faliszek discusses AI in this context because he believes gaming executives view it as a quick “idea generator” that could assist developers in brainstorming concepts and prototypes—potentially useful if a team member is unavailable. However, he argues that design isn’t a straightforward destination; it’s a journey, a “line” where creativity involves a human process of trial and error.

He recalls how Team Fortress 2 started as a military shooter, undergoing numerous identity shifts. What seems obvious in TF2 today was anything but during development. Even the fundamental question of who the characters are and their purpose was a complex challenge.

“Are they brothers fighting on a farm in the Midwest?” he posed. “Are they clones?”

Finding the answers to these questions didn’t rely on generating ideas quickly. It was the process of wrestling with concepts that ultimately led to a superior game.

“Deciding how silly they could be? Like the Soldier being the dumbest—’Hey, I’m surrounded on all three sides.’ That sparked a whole day of debate over that line.”

An AI might have suggested making the Soldier a clueless American, but the essence of what made it work came from the collaborative effort of people from various departments refining the finer details. Faliszek emphasizes that the uniqueness of TF2 emerged from everyone “showing the work,” rather than just someone throwing out a catchy idea and running with it.

Interestingly, Faliszek’s own experience at the time was somewhat unrelated: he was working on episodes of an apocalyptic TV show that ultimately didn’t materialize. That experience—and the struggle to make the initial concept work—eventually inspired the “Meet the Team” shorts that contributed to TF2’s popularity.

“To think you could shortcut that part of the creative process with AI? You’re going to prototype early on with AI and then build your billion-dollar franchise on that? No! No! Oh my god.”

The video runs nearly 10 minutes and is packed with intriguing insights for Valve enthusiasts—Faliszek even playfully hints at some lesser-known aspects of TF2. It’s definitely worth a full watch if you have the time.

The internet once hyped Cube World as the ultimate game, but it has yet to progress beyond alpha.
