The Line Between Cheating and Modding

This chapter explains the important distinction between modding and cheating in single-player games. It shows that while modding can extend replayability, encourage creativity, and strengthen community engagement, it can also become a pathway for tampering if clear boundaries are not defined. The chapter identifies protected systems that should never be moddable, including XP, currency, quest states, unlockables, enemy balance, save validation, and internal security logic. It also presents safe modding categories such as visual, audio, cosmetic, UI, and accessibility changes that do not alter core gameplay rules. Through a controlled Unreal modding API, the chapter demonstrates how developers can support creativity while keeping authoritative gameplay systems locked in C++. Overall, the chapter frames safe modding as a balance between player freedom and game integrity.
