What to Consider When Using Generative Content in Projects

The use of generative AI in game development opens new horizons, but it is important to realize that AI plugins are primarily intended for prototyping. Before integrating generated content into the final version of a game, it's important to carefully weigh all the pros and cons. This will help avoid potential problems and ensure a high-quality final product. It's important to remember that generative AI can only serve as an auxiliary tool, not a replacement for the developers' creative process.

It's crucial to ensure that the datasets used by neural networks don't infringe copyright. The Steam platform flags games that contain generated content, including artwork, code, and sound. Furthermore, projects using neural networks may lose their value in the eyes of users who are skeptical of such technologies.

When using generative AI in development, it's necessary to carefully consider artistic aspects, target audience expectations, and copyright compliance. Ignoring these factors can lead to unpleasant consequences, as happened with Activision. The company faced criticism for the six-fingered character on the Call of Duty: Black Ops 6 loading screen cover. Further analysis and adherence to standards could help prevent similar situations in the future.
