He explained that the game's difficulty slider is an embodiment of Bungie's philosophy that Destiny should be a game that suits players of all skill levels and moods.
"We're building lots of encounters, and even activities, where it's not immediately obvious what you should do. And in fact, you're going to fail," Green said. "Oh my god, you're actually going to play a AAA video game and fail a lot. When we say that we're building something for every mood, we really mean it."
Players will find Destiny's campaign to be more "accessible," Green said, noting that players looking to ease into the game after a hard day at work should start there.
Regarding Destiny's competitive multiplayer component, Bungie recently said that it will be "faster" and "more lethal" than what was featured in the Halo series.
Destiny officially launches for Xbox 360, Xbox One, PlayStation 3, and PlayStation 4 on September 9, 2014. Players will get a stab at the game in summer 2014, when a beta launches first on Sony platforms. For more on Destiny, check out GameSpot's previous coverage.
