A sandbox game is a video game with a gameplay element that provides players a great degree of creativity to interact with, usually without any predetermined goal, or alternatively with a goal that the players set for themselves. Such games may lack any objective, and are sometimes referred to as non-games or software toys. More often, sandbox games result from these creative elements being incorporated into other genres and allowing for emergent gameplay. Sandbox games are often associated with an open world concept which gives the players freedom of movement and progression in the game's world. The term "sandbox" derives from the nature of a sandbox that lets people create nearly anything they want within it.

A fan game is a video game that is created by fans of a certain topic or IP. They are usually based on one, or in some cases several, video game entries or franchises. Many fan games attempt to clone or remake the original game's design, gameplay, and characters, but it is equally common for fans to develop a unique game using another as a template. Though the quality of fan games has always varied, recent advances in computer technology and in available tools, e.g. through open source software, have made creating high-quality games easier. Fan games can be seen as user-generated content, as part of the retrogaming phenomena, and as expression of the remix culture.

Epic Games, Inc. v. Apple Inc. was a lawsuit brought by Epic Games against Apple in August 2020 in the United States District Court for the Northern District of California, related to Apple's practices in the iOS App Store. Epic Games specifically had challenged Apple's restrictions on apps from having other in-app purchasing methods outside of the one offered by the App Store. Epic Games's founder Tim Sweeney had previously challenged the 30% revenue cut that Apple takes on each purchase made in the App Store, and with their game Fortnite, wanted to either bypass Apple or have Apple take less of a cut. Epic implemented changes in Fortnite intentionally on August 13, 2020, to bypass the App Store payment system, prompting Apple to block the game from the App Store and leading to Epic filing its lawsuit. Apple filed a countersuit, asserting Epic purposely breached its terms of contract with Apple to goad it into action, and defended itself from Epic's suit.
