Early access, also known as alpha access, alpha founding, paid alpha, or game preview, is a funding model in the video game industry by which consumers can purchase and play a game in the various pre-release development cycles, such as pre-alpha, alpha, and/or beta, while the developer is able to use those funds to continue further development on the game. Those that pay to participate typically help to debug the game, provide feedback and suggestions, may have access to special materials in the game. The early-access approach is a common way to obtain funding for indie games, and may also be used along with other funding mechanisms, including crowdfunding. Many crowdfunding projects promise to offer access to alpha and/or beta versions of the game as development progresses; however, unlike some of these projects which solicit funds but do not yet have a playable game, all early access games offer an immediately playable version of the unfinished game to players.

In video games, skin gambling is the use of virtual goods, often cosmetic in-game items such as "skins", as virtual currency to bet on the outcome of professional matches or on other games of chance. It is commonly associated with the community surrounding Counter-Strike 2, but the practice exists in other games such as Electronic Arts's FIFA. Valve, the developer of the Counter-Strike series, also runs the Steam marketplace which can be interfaced by third-parties to enable trading, buying, and selling of skins from players' Steam inventories for real-world or digital currency. Valve condemns the gambling practices as it violates the platform's terms of service.

PUBG: Battlegrounds is a 2017 battle royale video game published by Krafton, and developed by Krafton's PUBG Studios. The game, which was inspired by the Japanese film Battle Royale (2000), is based on previous mods created by Brendan "PlayerUnknown" Greene for other games, and expanded into a standalone game under Greene's creative direction. Played from either a third-person or first-person perspective, up to one hundred players parachute onto an island where they are tasked to scavenge for weapons and equipment to kill other players while avoiding getting killed themselves. The available safe area of the game's map decreases in size over time, directing surviving players into an ever-tightening space to force encounters.
A battle royale game is an online multiplayer video game genre that blends last-man-standing gameplay with the survival, exploration and scavenging elements of a survival game. Battle royale games involve dozens to hundreds of players, who start with minimal equipment and then must eliminate all other opponents while avoiding being trapped outside a shrinking "safe area", with the winner being the last player or team alive.
