Season pass (video games) in the context of "Expansion pack"

Downloadable content (DLC) is additional content created for an already released video game, distributed through the Internet by the game's publisher. It can be added for no extra cost or as a form of video game monetization, enabling the publisher to gain additional revenue from a title after it has been purchased, often using a microtransaction system.

DLC can range from cosmetic content, such as skins, to new in-game content, like characters, levels, modes, and larger expansions that may contain a mix of such content as a continuation of the base game. In some games, multiple DLCs (including future DLC not yet released) may be bundled as part of a "season pass"—typically at a discount rather than purchasing each DLC individually.

Buy-to-play (B2P) is a revenue model for video games where a game can be played after a one-time purchase, as opposed to a subscription model where the player must pay a subscription at regular intervals to continue having access to the game.

Buy-to-play, while a form of premium games, generally apply to games where there is continued ongoing content or support from the developer or publisher well beyond the period of purchase, such as through maintenance of online servers or through the production of ongoing content and expansions, as often the case in massively multiplayer online games (MMO). This support can be monetized through additional microtransactions or through an ongoing subscription fee. Microtransactions are becoming evermore entwined with the buy-to-play revenue model as most recent games allow for some sort of additional purchase. For example, buy-to-play title Guild Wars 2 allows players to purchase additional in-game items with microtransactions, while Destiny 2 lets users purchase season passes for additional content.
