rejection

The video game industry receives a controversial experiment that some already describe as dystopian, although in reality it has much of a privileged look at a reality that is, potentially, around the corner. ‘Codex Mortis‘ is a title that is openly presented as the first video game developed entirely using artificial intelligence, which has released its demo version on Steam and has immediately unleashed a divided (but mostly hostile) response among the gamer community. What did you sew? The project, signed by a developer who signs with the pseudonym Grolaf, has generated controversy for its shameless proposal (a clone of the acclaimed indie hit ‘Vampire Survivors’, one of the great surprises of recent years, but replacing the delicious retropixelated aesthetic with the blurry and rough aesthetic typical of generative systems). But also, as it could not be otherwise, it has reopened the debate about the ethical and creative limits of AI in video game development. It comes at a time when major studios are facing similar accusations and sectors such as voice actors are organizing strikes against these technologies. I don’t like it. In the Steam community reviewsthe demo registers only 60% positive ratings among around thirty reviews, with comments that range between technical curiosity and, above all, outright rejection. The press has not been much more generous, and some means gives it the dubious honor of being “a foundational milestone of poorer AI.” Various websites They have collected opinions from players as strong as “games are ART. They need soul, life, virtue. Something that AI will never be able to capture”, which define the game as “machine-generated garbage.” How it was born. ‘Codex Mortis’ was developed over three months in which Grolaf exclusively used artificial intelligence tools to build all elements of the game. The developer used ChatGPT to generate the images and Claude Code to write the code. As a programming language it used TypeScript, instead of traditional engines such as Unity or Unreal Engine. The technical architecture is supported by libraries such as PIXI.js for graphics and Electron for desktop execution, a decision that apparently makes it difficult to correct errors, since the developer does not fully understand, by his own admission, how the systems generated by the AI ​​interact. The lightning that does not stop. The negative reaction to ‘Codex Mortis’ is not isolated, but the latest episode in a battle that has been shaking the industry for months. In November, for example, ‘Arc Raiders‘, Embark Studios’ extraction shooter, received a score of 2 out of 5 from Eurogamer exclusively due to its use of AI-generated voices. This rating sank the title’s Metacritic from an impressive 94 to 86, sparking a debate on whether the use of AI should be considered in critical assessments. Controversy escalated when the game received a single nomination at the Game Awards, leading many gamers to accuse the awards of deliberately punishing the title for its technology. Another case: ‘Call of Duty: Black Ops 7’ included clearly AI-generated assets (with characters with the typical six fingers, among other visual irregularities characteristic of AI). The scandal forced Activision to issue supporting statements given the disclosure policy on the use of artificial intelligence that Valve requires to include in games sold on Steam. Rejection among professionals. The State of the Game Industry 2025 survey from the Game Developers Conference reveals a drastic change in the perception of AI by professionals: just 13% of developers consider that generative AI will have a positive impact on the industry, falling from 21% the previous year. The percentage of those who see it negatively shot up from 18% to 30%. The most revealing part of the study is who adopts these tools: 50% of the professionals are from Business and Finance, followed by 40% in Production and Marketing. However, among programmers and artists, the true creators, adoption is significantly lower. 87% of developers surveyed expressed concern on the impact of AI on the industry. In Xataka | Someone put ChatGPT, Gemini, Claude and other AIs to play a kind of Risk. The results could not be more different.
