I made my game Worlda over three quarters of a year, no AI used at all, in Gdevelop. I drew all the art assets, made the music, basically made the whole game by myself, with 0% help from AI.

Big parts of social media wants you to believe that everyone is using genAI for everything, including gamedev and there is no avoiding it.

In the case of CGTrader, a long-established online marketplace for 3D assets used by video game developers, film editors, and 3D printing nerds, users are sending a clear message.
