Did you once notice the lack of footprints or think "gosh, this game would be so much more fun if I could shoot the glass out of those lanterns in a realistic fashion" at some point?
Destiny relies on the Diablo game mechanics. Do the same shit repeatedly for better drops to do more shit repeatedly for better drops AND you can only save progress periodically. Diablo perfected that Carrot/Stick approach to videogaming and it was a lot of fun even though it was repetitive. Destiny for me was fun once I hit level 40 and then right up until I needed a full team to get better gear. The problem is, since Diablo pretty well perfected the Carrot/Stick with random drops and occasional saves back about 20 years ago...now we're just adding fluffy bullshit. The game is average because it's the same damn thing, just dressed up differently.
For me, games I'm interested in now either need a good story (Last of Us, Uncharted) so it's like a playable movie, carrot/stick (preferably with numbers I can watch go up), or be a sandbox type game with a shit ton of varied content. I don't care if there's 17 types of grass tiles or if there's lens flare or if the rain hits the pond's surface and causes ripples to expand just like in real life. I want to blast alien faces, get cool loot, and make decisions that matter.
