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

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.

Hearthstone is a 2014 online digital collectible card video game produced by Blizzard Entertainment, released under the free-to-play model. Originally subtitled Heroes of Warcraft, Hearthstone builds upon the existing lore of the Warcraft series by using the same elements, characters, and relics. The game is available on the Windows, macOS, iOS and Android platforms, featuring cross-platform play. It has been a critical and commercial success, with Blizzard reporting more than 100 million Hearthstone players as of November 2018, and the game has become popular as an esport, with cash prize tournaments hosted by Blizzard and other organizers.

The game is a turn-based card game between two opponents, using constructed decks of 30 cards along with a selected hero with a unique power. Players use their limited mana crystals to play abilities or summon minions to attack the opponent, with the goal of destroying the opponent's hero. Winning matches and completing quests earn in-game gold, rewards in the form of new cards, and other in-game prizes. Players can then buy packs of new cards through gold or microtransactions to customize and improve their decks. The game features several modes of play, including casual and ranked matches, drafted arena battles, and single-player adventures. New content for the game involves the addition of new card sets and gameplay, taking the form of expansion packs.

Unreal Tournament is a 1999 first-person shooter game developed by Epic Games and Digital Extremes. The second installment in the Unreal series, it was first published by GT Interactive in 1999 for Windows, and later released on the PlayStation 2 and Dreamcast by Infogrames in 2000 and 2001, respectively. Players compete in a series of matches of various types, with the general aim of out-killing opponents. The PC and Dreamcast versions support multiplayer online or over a local area network. Free expansion packs were released, some of which were bundled with a 2000 re-release: Unreal Tournament: Game of the Year Edition.

Powered by the Unreal Engine, Unreal Tournament received universal acclaim, often being considered one of the greatest video games ever made, with reviewers praising the graphics, level design and gameplay, though the console ports were noted for having limitations. The design of the game shifted the series' focus to competitive multiplayer action with the releases of sequels Unreal Tournament 2003 in 2002, Unreal Tournament 2004 in 2004, and Unreal Tournament 3 in 2007.

For this list, sales figures must be directly attributed to a franchise to be included. In instances where overall figures for a franchise are not known but sales of a single game within that franchise are, sales for that game will be attributed to the franchise. Sales of expansion packs and episodic video games are included. Metrics such as "players" or "installs" are not listed as they typically refer to user engagement rather than sales; even for paid games, these metrics could include free trials or other free promotions and cannot reliably be substituted for sales figures.
