Destiny 2. I played THE HELL out of Destiny 1, then 2 rolls around and it was like they forgot everything that people liked about 1.

You couldn't access the story missions from the map, and you couldn't replay them on demand, you could only play them off a playlist. There was a weekly heroic story mission that gave a powerful engram reward, then they removed the reward and people stopped playing even that. Eventually they removed the story missions entirely "because nobody was playing them". Big brain move there!

In Destiny 1, each series of missions on a planet ended with a higher level "strike". So you'd pick the missions off the map based on your light level, then level up to hit the strike, then move on to the missions on the next planet.

In D2, not only could you not see the missions, or what level you were supposed to be, the strikes weren't present on the map at all, you could only play them on a play list and the play list was randomized. It was also bugged, often delivering the same strike over and over and others not at all, leaving gaps in the storyline and player experience.

They did patch things, like being able to play strikes on demand, then about 1/2 way through the life cycle Bungie decided to just delete 1/2 of the content in the game. New players would come in, have no access to the original story missions, no idea what was going on, and no idea how to proceed without watching a bunch of youtube videos showing the content removed from the game.

For existing players, they decided that people had spent too much time, in some cases hundreds of hours, curating their perfect weapon and armor sets. Rather than create better gear to replace what people loved, they artificially capped old gear to sunset it and force people to "upgrade" to crappier gear that replaced it. They intentionally didn't make better gear because they were afraid of "power creep" and legitimately "explained" that they no longer knew how to design the game around the old gear. Funny, they didn't have that problem when it was the ONLY gear.

Maybe it's better now? I dunno, the way Bungie totally disrespected the time I spent playing and money I spent on expansions, they'll never get another dime from me.
