Destiny 1 had incentive, Destiny 2 does not. Destiny 1 was super lackluster in content, but you could grind out strikes and crucible for the weapon rolls, which is replayability. Destiny 2 has the content going for it, but no replayability. As for the three character argument that everyone like to bring up - replaying a campaign and doing the same things on multiple characters does not equal content lol. You play the same missions, in the same zones as the time before turning in the same tokens for the same gear, doing the same exotic missions for the same exotics. The only thing that changes is my fire sword is now a fire gun. Yay content.
