We have two vastly different stories about how AI and AI slop is negatively impacting both the Unity and Godot game engines, for vastly differing reasons.
First we have the problem that Godot (and many large open source projects) are facing – an absolute deluge of LLM generated AI Slop code being submitted. The ability for just about anyone to generate code, often code they do not fully understand, has created a massive burden for project maintainers. From a PC Gamer article on the subject:
In a Bluesky thread (via Game Developer), Rémi Verschelde—one of the primary maintainers of the Godot Github repository and co-founder of major Godot backer W4 Games—says the problem of “AI slop” pull requests, or requests to merge code changes with the project, is “becoming increasingly draining and demoralizing for Godot maintainers” as they’re now forced to deliberate the trustworthiness and human authorship of an onslaught of LLM-generated contributions.
“We find ourselves having to second guess every PR from new contributors, multiple times per day,” Verschelde said. “The description is verbose LLM output; is the code written at least partially by a human? Does the ‘author’ understand the code they’re sending? Did they test it? Are the test results made up?”
Even if Godot’s maintainers are able to identify AI-generated code or description, Verschelde says that’s often just the first of compounding complications.
“Is this code wrong because it was written by AI, or is it an honest mistake from an inexperienced human contributor?” Verschelde said. “What do you do when you ask a PR author if they used AI because you’re suspicious, and they all reply ‘yes I used it to write the PR description because I’m bad with English’?”
Verschelde says Godot “prides itself in being welcoming to new contributors, letting any engine user have the possibility to make an impact on their engine of choice.” But navigating the accelerating rate of PRs that could jeopardize the project’s health with faulty code or incomplete understanding is overtaxing the maintainers’ finite capacity.
“Maintainers spend a lot of time assisting new contributors to help them get PRs in a mergeable state,” Verschelde said. “I don’t know how long we can keep it up.”
Unity on the other hand is facing a much different “problem”… the stock market. Unity is a publicly traded company and fair or not, Unity is being lumped in with AI stocks. This can lead to massive volatility (such as the massive 25%+ drop when Google Genie 3 was unveiled) from investors that don’t really understand the industry. This has in the past lead to Unity chasing features that much of it’s user base do not wont, in order to keep investors happy. New CEO Matt Bromberg is being forced to walk that tight rope of keeping developers happy while also pleasing investors, two priorities that often do not align. This is reflected in the recent announcements of AI focus at Unity from Game Developer:
“AI-driven authoring is our second major area of focus for 2026,” said Bromberg. “At the Game Developer Conference in March, we’ll be unveiling a beta of the new upgraded Unity AI, which will enable developers to prompt full casual games into existence with natural language only, native to our platform—so it’s simple to move from prototype to finished product.”
“This assistant will be powered by our unique understanding of the project context and our runtime, while leveraging the best frontier models that exist. We believe together this combination will provide more efficient, more effective results to game developers than general-purpose models alone.”
Bromberg claimed Unity AI will “democratize” game development for non-coders while raising productivity for all users.
“Our goal is to remove as much friction from the creative process as possible, becoming the universal bridge between the first spark of creativity and a successful, scalable, and enduring digital experience,” he continued.
