It feels really good as a player to know that the people actually making the game you play are listening to fan feedback.
That's part of what's kept me interested in "Destiny" over all of these years. Yes, the game is constantly growing, and there's a ton of stuff to do at all times, but that's because players have gradually molded the game into something they want to play more of. Through constant suggestions and constructive criticism on Bungie's forums and Reddit, Bungie has implemented many of the best ideas to make the game more fun, deep, and playable.
Players wanted to see lore in the game; Bungie added the ability to read any and all lore, right in the game, instead of having to visit a website to read about the world of "Destiny" (this was the case previously). Players wanted a place to house their many accomplishments, and enjoy a no-pressure shooting gallery to test out weapons; Bungie added the Tribute Hall this month, which offers all of the above. Players wanted more secret missions, and surprises; Bungie has added a handful of secret questlines that reward unique gear. The list goes on.
Considering how far "Destiny" has come since September 2017, I'm looking forward to seeing how the game will change and grow in the years to come.
