Cheating in game development is more about finding bugs and glitches than intentional wrongdoing. Most game AIs are incapable of intent, but they can still find ways to exploit game mechanics.

An AI playing Sonic the Hedgehog found an unintended shortcut to outperform traditional players by glitching through walls on underwater levels.

Developers need to be aware of the potential for AI to find new bugs and glitches to exploit. It should be standard practice to get an AI to play games as a routine part of QA testing.

A bit of luck can help developers discover things about their game that they didn't know themselves.

Machine learning is a crucial aspect of video games, and it comes in many forms. One of the most fascinating types is Genetic Neural Networks.

Genetic neural networks can run simulations with known outcomes, but without showing the process. They can figure out the best approach to reach a specific outcome, like reversing population health data during a pandemic.
