So the first Destiny is pretty skippable IMO. There’s nothing in there story-wise that you need to understand Destiny 2, other than world and character building. Everything the first one does the second one does better, at least from a single player story/quest perspective.
The real issues I had with the first game were that the missions just felt tacked on, like they had all these lovely open world multiplayer spaces and then decided to add single player quests to them without really spending any time crafting either a narrative or mission structure. The constant reuse of environments for different missions was quite jarring too.
This problem is resolved entirely in the sequel, which has a pretty compelling story actually for what is essentially an MMOFPS. The campaign missions are for the most part their own environments, which do not exist in the multiplayer space. The plot has proper arcs and makes you feel like you’re actually making a difference to the world. The only problem is its a little short, something not addressed in either of the free to play expansions, Curse of Osiris (bland), and Warmind (good!).
I’ve signed up for a month of Xbox Live Gold to play some of the multiplayer, which is pretty varied and satisfying. I’m absolutely rubbish, it’s been a long time since the heady heights of my Halo 2 days, but it’s a lot of fun actually. The game has surprised me. I’m not convinced there’s enough here to keep me playing after I’ve gone through everything because it looks to be pretty grindy once you’ve exhausted the variety, but for a month it will keep me very happy.
