For anyone new to game development the rise in end-to-end game AI developer platforms, such as Rosbud and Layer, could be the ideal entry point. These platforms can take you from text description to final game, creating art, animation, NPCs, scripts, coding - everything. These are new platforms and users need to agree to the data use, and there could be commercial restrictions. You can generate art on a platform like Layer, or train it on your own art. Games can be created from scratch, from templates or from cloning existing games made in the apps. Even if these don't end up being your finished game, for newcomers this kind of AI platform could be a way to get into game creation and devise prototypes.
