How was Division 1, anyway. After all is said and done I mean.
Dark Zone is shit and they never did much to actually make it worthwhile.
PvP is shit (but that's obvious with how RPG-nature the game is, like Destiny's).
PvE didn't get much in the way of updates to the story (no continuation mission patched in to send you off to DC... yet...?). Underground, Survival (kinda), and a Hoard mode are about it, but nothing story-wise.
Survival is the star of the DLC. Worth playing the game for that mode alone (too bad it's kinda dead now).
If you can get it for $15 or so, with the DLC pass it's worth a quick run through if you're needing a loot shooter a la Destiny.
I'm kinda disappointed that we didn't get a lot more of NY than just Manhattan's lower side (with Central Park being part of the Dark Zone IIRC) and Brooklyn for like 15 mins max.
