Ok wow.
Let me break this down a bit for non players.
D2’s business model has been criticized by players quite heavily the past few months. The most well known was brought up by Destiny streamer/content creator Azteccross in his video about the game calling it a ‘microtransaction hell’. It got a million and a half views on its own, Asmonggold’s reaction video to it got a million a half views also and other reaction videos drew hundreds of thousands of views also. The crux is that D2 has turned into a bloated and expensive game to get into and how Bungie decided to focus on paid cosmetics with some questionable pricing schemes hidden behind tricky currency nonsense.
To deal with the criticism they decided on one of the things they wanted change from a seasonal content model into a chapters based system. The seasonal model was a 3 month dlc drop that stayed up for no more than a year with 4 drops. After that year is up, most of those missions and content outside of weapons, armor and cosmetics just goes away. They tried to drip out content little by little week after week. The players called them out for how predatory this model is by abusing fomo.
The chapter format that was supposed to come out early next year alongside the Final Shape was supposed to change things up. 3 expansions over the year containing 3 spaced out content drips throughout the chapter, spaced 4 months apart and the content will be permanently added to game.
I guess Bungie likes their new(ish) baby Marathon more because it that could have the potential to get new players than the esoteric, bloated and expensive Destiny 2
Edit: might as well include the video I mentioned. It’s a long one with a 35 minute viewing time
