I played DDDA years ago and really enjoyed it and replayed it a few weeks before 2 came out so I can actually compare some things accurately while the original is still fresh in my memory.
I think DD2 is a worthy sequel, but not necessarily superior to DD1 (or more specifically, to DDDA, as I've never played the vanilla DD1).
Some things are vastly improved, namely the scale and design of the world, the behaviors of the monsters and NPCs and their interactivity with the game world and its mechanics, the endgame (more on that below), stuff like gold actually mattering more because you get less of it and things cost more, etc.
Some things are sidegrades, like the vocation system - some of the new changes are great, some are bad. Mystic spearhand is extremely fun, trickster is not. I feel like mages and sorcerers got hit by it the hardest, as other than being able to use only 4 skills they just get less spells in general for some reason. In DDDA mages got 2 spells of each element + healing and buff spells and sorcerers got 3 of each element + other spells like necromancy and maelstrom. Here it's 1 spell per element for mages + smaller number of heal/buff spells and 2 spells per element for sorcerers and fewer non-elemental spells. On the other hand, the ability to quickcast and hold a cast spell are awesome additions.
Some things are straight downgrades - the simplified gear system, the clunkier movement, the music, while not bad, felt blander than DDDA's, quantity over quality approach when designing dungeons and NPCs.
Unfortunately in some aspects the game feels just as weird and unfinished as the first game, namely the story and the main quest.
First 30-40 hours I was just happily running around and exploring and doing side quests and ocasionally progressing the story a little bit. The whole situation with the imposter arisen and court intrigues seemed interesting. As you progress the main quest and certain side quests you learn more and more about a certain Phaesus, who seems to be opposing you. Then you learn about that artifact that the imposter uses to control pawns and are sent to Battahl and by that time I was still on board with the story and was interested to see where it goes.
I got to Batthal and started doing side quests there. I noticed that the region seemed quite a bit smaller than Vermund and also lacked any completely new monsters, just some reskins of existing ones + the medusa which you had already seen in the tutorial, which was a bit disappointing. Then I started progressing the main quest and the whole thing just started falling apart. First you collect some magic stones for some loser who's barely introduced to you, then you have to deliver them to the magic lab, which the game implies is some off-limits facility and maybe you need a disguise or to do a quest... JUST KIDDING, you can just walk in there lmao. Then you rest for a day, come back to him, he gives you the Godsbane and asks to deliver it to Phaesus. At this point I wondered why am I running errands for the guy who was clearly shown in the cutscenes to be behind all the shady shit going on in the capital and was clearly opposing me. I know it was the Seneschal/Pathfinder force persuading the scientist into entrusting the godsbane to me to deliver to Phaesus, but I was still very confused about the whole thing. Then the Talos sequence starts and... that's actually basically the end of the game. Talos, while spectacular and cool looking, was a very boring fight, that consisted of climbing onto his weak points and mashing the attack button for 20 seconds, repeat. At that point I was kinda getting tired of the game and the very disjointed series of story events wasn't helping. Then you got to the mining facility and already you are at the final dungeon. Unlike the final dungeon in DDDA, there are no enemies to fight, except for the false arisen and his pawns, which I thought was kinda cool. Then Phaesus basically plays the role of the Salvation cult leader in DDDA - spouts some gibberish and gets shut up by Grigori.
In the end this whole plot with Phaesus and the queen conspiring against you seemed as incosequential in the grand scheme of things, as the subplots involving the Salvation cult, Mercedes and that other french guy in DDDA. None of these things went anywhere and ultimately didn't matter.
The final fight with Grigori was disappointing as well. No spectacle like in DDDA, you just fight him in an arena and he's just another drake, but larger in size.
Then the game just ends. I knew of the existance of the post-game zone, but getting to it was not as straightforward as in DDDA, where you just have to kill the dragon (why wouldn't you, you ain't no bitch, are you?). You get a matrix-style red pill/blue pill sequence during the end credits, which made me think that this is DEFINITELY the place you decide wether to have a standard ending or the Everfall ending, but it just puts you back before the fight with Grigori. I actually had to look it up - you need to use the Godsbane, which I honestly forgot I had in my inventory.
So I get to the Unmoored World and... holy shit. The title drop. The title screen change and the depressing music. The change in mood and atmosphere. The expanded game world. All the lore implications that slowly make you realize where exactly you are. All the new monsters and bosses that appear all over the place. It left quite an impression on me and reignited my love for the game and made me forget all the boring, incosequential bullshit I was doing up to this point.
It's such a cool end game/true ending sequence that basically turns the entire world into Everfall complete with new quests and game mechanics.
In my opinion, they should have revealed this much earlier and made it a bigger part of the game and last for a longer time. Some other criticisms:
1. They should be upfront about all the mechanical changes in the Unmoored World. I thought that the destruction of the world is tied to the passage of time but time actually stands still in the Unmoored World unless you rest. Also, if you die you apparently can't reload your saves and have to go back to the start of the Unmored World or to the last bed save, but it wasn't a problem for me and the couple dozen wakestones I've been hoarding during my playthrough.
2. At that point in the game, my party was very very strong so even the new monsters of the Unmoored World and the Brine mutated dragon bosses posed no challenge.
3. There wasn't a proper end game superboss. There wasn't one in DDDA as well - the Seneschal was a joke, but when the giant dragon 5 times the size of Grigori showed up, I thought "here it is, the badass dragon fight I've been waiting for", but it was just a cutscene where you slowly walk around on its spine occasionally avoiding projectiles while the Pathfinder vomits lore at you.
Still despite that, extremely cool sequence of the game that managed to impress me even though I was aware of its existance. I feel sorry for all the people who missed it because it is extremely easy to miss, especially if you didn't play DDDA and don't expect an Everfall-style twist and don't know what a Godsbane is.
So, all in all, really great game, but it still felt a bit disappointing because it could have been so much more. A big part of why DD2 is great are the robust core gameplay mechanics that were already in the first DD and they just had to port them over to a new engine. I really, really wish there was more fun and interesting content, like more new monsters, vocations and dungeons that could let you play around with these mechanics more. I think that had DD2 come out 3-4 years after 1, it would have been a better game, because they wouldn't need to spend resources moving everything that already worked to a new engine.
The launch was also extremely shoddy. The performance is unacceptible, but the microtransaction fiaso is extremely overblown by clickbaiting grifter retards. It's literally just Deluxe edition content that you can buy separately if you want and all of the things, except the DD1 soundtrack, are available in game in great quantities.
I really hope that they don't just abandon this game because it didn't sell 10 million copies and polish it up with updates and maybe a meaty expansion like Dark Arisen, or two. I can totally see myself replaying it in the future.
Probably gonna end up being my GOTY this year. The only things that can threaten its position are the Wukong game being very good or Labyrinth of Touhou 3 coming out this year, both of which I highly doubt.
Thank you for coming to my TED talk.
