What are the most worthwhile DLCs you've played?

Witcher 3's Blood and Wine Expansion was incredible. Added so many more hours of new content to do that it felt like an entire new game.

Fallout: New Vegas had some pretty phenomenal DLCs, and even went to the trouble of interleaving story threads and characters between all of them, though subtly. All of them were excellent (even Honest Hearts), and had all the side quests, choices, writing quality, and branching storylines that made the main game what it was, but Old World Blues was definitely my favorite.

I personally loved Bioshock Infinite's Burial at Sea part 2. The opening and ending scenes are really rich and memorable. It's in many ways a tighter and better told story than the main game, and I feel like it represents the best of what Irrational Games was trying to achieve with their games -- right before the studio was closed. I know some people had mixed feelings about the character arcs, but I was totally satisfied by the ending. If this DLC is our last view of Rapture, I think that it ends on a really high note.

Mass Effect 3: Citadel

It was the “goodbye” we didn’t get in the base game and you can tell the developers took it as their final love letter to the characters.

You go on missions with various squad mates from all three games to uncover this dastardly plot against Shepard but along the way, you have fun. You can go into an Arena mode with different squad mates, go to a bar and dance(albeit as part of a mission), and it all culminates in a legit house party where Grunt, after you bail him out of Citadel jail, has entirely too much fun being the door bouncer, memories are had and even a couple one night stands can occur.

You can play it fairly early on but it’s definitely meant to played right before you start the final mission.

Blood and Wine for The Witcher 3 is fantastic. I tremendously enjoyed the other expansion Hearts of Stone for that game too, but imho B&W is even better.

Tiny Tina's Assault on Dragon Keep for Borderlands 2 is without a doubt the best BL2 DLC and generally really good.

Hands down, Far Cry 3 Blood Dragon. No DLC has done 'better than the original' more than that DLC did.

Do Hearthstone adventures count? They're the only paid "DLCs" I've played that were actually unique, interesting content (rather than "more of the same" like in Civ).

I liked the Borderlands DLCs but I always felt just… completely ripped off by Borderlands as a whole. I love the game but I hate the way they do DLC.

I think The Talos Principle's Road to Gehenna DLC is one of my favorites. I loved the game, and it added more interesting puzzles and good writing. The general themes were around isolation and online communities as well, and I thought it was really well done.

I also recently played through the Hacknet Labyrinths DLC and enjoyed it quite a bit too. It had more of the stuff that I liked from the main game (including more excellent music), and I felt like the missions also required a little more "digging" than the main game did. There were a few situations that I ended up feeling pretty clever when I figured them out, and I think there was at least one section that I managed to solve in a way that wasn't actually intended but still worked.

• Uncharted 4's Lost Legacy & The Last of Us Left Behind. Both great for being standalone installments that were their own great stories. I think Naughty Dog knew just how to create stories that were great additions to the main story, or served as good toes-dipping-in-water for newbies.

• Dying Light's The Following. IIRC it unlocked a map bigger than the starting map, added vehicles, and a bunch of other new stuff. Those developers seemed especially nice to their community.

• I didn't care for Heavy Rain, but I thought its DLC was a perfect standalone chapter: you were the reporter investigating a lead, which was just some suspicious guy's house. you went in on your own and nobody was home. while searching the house your character would make floor boards creak, you could open a cupboard, etc.-- then, midway through your search, after finding something especially incriminating, the guy comes home. now you have to remember where the floorboards were that creaked, what clues you left behind for him to see, etc., and escape! It was a perfect standalone story that could've been its own thing.

Breath of the Wild's DLCs made the $20 pass completely worth it. When I first got the game at launch, it was basically an extended post-game because I'd beaten the game before the DLC rolled out (they were still finishing it, I think), but I then got my switch (and BOTW, and the DLC pass again), and played through it on normal mode. The mid-game changes this DLC adds made it feel like a new game. My typical experience is "this is stuff they should have put in in the first place!" but the additions really just make the game more interesting in different ways.

At least for their main games that I've bought, Nintendo's DLC, usually via season pass, is worth it most of the time. The only time I felt screwed was Mario Kart 8, but I bought my Wii U just before Nintendo killed the system.

The DLC for Dark Souls 2 is top-tier. Crown of the Ivory King might be my favorite part of the entire series, and Dark Souls 2 is my least favorite. Only thing, though, is that they are HARD. If you thought the base game was tough then youre really in for it.

Afterthoughts:

1. Civilization: Beyond Earth is essentially just Civ5 with a science fiction reskin. It is a very good reskin but that is all it is. The Rising Tide expansion, however, makes it an entirely unique game, and a very good one.
2. The expansions for Shovel Knight are all complete games, arguably better than the original.

I don't often get DLC, but Battlefield 3's Premium was really worth it, to me. You got access to many more maps, and, in an FPS, a new map is a huge extension to replayability. Granted, they changed their DLC model in BF4, BF1 and BFV, because making maps exclusive fragmented the community (ostensible PR-speak for: cost the company more money because servers were underpopulated).

Bioshock 2 was better than it had any right to be, and the Minerva's Den DLC was even better. It tells another intriguing story in Rapture with a new weapon and new enemy in a handful of hours.

Dishonored's The Knife of Dunwall and The Brigmore Witches are two parts of the same story running parallel and a bit beyond the original. You play as another character in the Dishonored story, with new powers. They're both fantastic and nearly add up to the same amount of gameplay as the base game itself.

The amount of content that the DLC for Assassin's Creed Odyssey adds to an already massive game is probably it for me. Full quest lines, new locations and so much stuff it makes buying their higher tier editions of the game worth it.
