Gave Div 1 an honest shake after having it in my library for 7 years and I'm nearly at the epilogue. It definitely didn't live up to the pre-release hype. Story doesnt really go anywhere outside of teasing some novel ideas like concerns over whether The Division waves are good for the people or an extremely morally grey area, the more interesting ideas are locked behind audio logs and those reconstructed flashback things. And missions can be repetitive and the online requirement sucks.
Gunplay is fun though on the higher difficulties, map setting is well fleshed out too and still very appealing despite the visual downgrade. The gameplay loop is pretty addicting, especially when you get to the end game and you can unlock higher world tiers. The Dark Zone is definitely my favorite element in the game, for a pre-extraction shooter it still does a lot right. There's elements in here that are pretty good, not hard to see why it still has a cult following. Helps that compared to something like Destiny its very playable on Linux.
