User: What makes Destiny 2 a popular game?
Assistant: Destiny 2 is a very popular first person shooter video game that was developed by Bungie, and is currently free to play on all major video game consoles and personal computers. Since release, Destiny 2 has released numerous additional content through expansion packs and seasonal content that expands the storyline and background lore of the universe in which the game takes place as well as new locations to explore and activities to engage in.

In Destiny 2, players assume the role of Guardians, who are gifted with the power of "Light" that allows them to protect the remnants of humanity that survived a catastrophic event of an event called "The collapse." This science fiction background and futuristic aesthetic combine to provide both a story-rich and feature-rich gameplay experience.

Destiny 2 is classed as a "looter shooter" first person shooter, which is a sub-genre of video games that feature procedurally generated equipment and weapons which encourages players to replay game content to achieve the best possible combinations of benefits from the items they receive. Furthermore, Destiny 2 is also commonly referred to as a  role playing game, elements of which allow users to customize their characters abilities and appearance and specialize in certain roles within the game. As new content is released into the game, this encourages players to experiment with new abilities, weapons, and equipment to achieve optimal performance and creates a satisfying gameplay loop or experience.

The game features two main modes of play. The first, which is classified as "Player Versus Environment", or PvE, pits the players against AI-controlled enemies in either solo content, group content (called fireteams) of 3 players, or raids of up to 6 players. Players team up in fireteams and raids to tackle more challenging content and in turn are rewarded with more unique or rare pieces of equipment. Additionally, there are "Player vs Player", or PvP modes in the game that allows players to compete against each other in competitive modes against each other. Both modes feature exclusive gameplay modes, locations, and objectives.

Finally, Destiny 2 features a rich cast of diverse actors and actresses that lend their voice talent to the game for their characters, such as Nathan Fillon, Lance Reddick, Nolan North, Lennie James, and many other noteworthy artists. 

Destiny 2 has also been nominated for and/or won several awards since release, including the Game Critics Award for Best PC Game (2007) and Best Ongoing Game (2019).
