Some things better, some things not. From gameplay experience, I think PoE2 is overall better (even though I did like so, of PoE1 systems). More refined system, more transparency in class progression, about the same length, but “less filler more killer”.
Where I think PoE2 falls short is companions and narrative. Not that there isn’t a lot of good stuff to enjoy there - worldbuilding is probably better, as you won’t have to resort to book reading to understand broader context. Deadfire’s history, culture, and political situation is neatly conveyed through engaging quests, rather than plain text. I also don’t think story is bad per say - I enjoyed every minute spent in three of my Deadfire playthroughs.
The game is very open ended though, and the narrative doesn’t have strong sense of progression. While PoE1 ending give an interesting perspective to everything we have been through, PoE2 ending feels like a set up to be followed up on. I felt there wasn’t sufficient pay off to our adventure in the Deadfire, and the ending made my gasp for PoE3. And with PoE3 not happening in foreseeable future I see it as a bad thing.
in short, I felt the beginning and end were the weakest part of Deadfire. Everything inbetween is pretty darn good. And of course, all three DLCs strongly recommended. They are more of a smaller side adventures this time around, but we’ll worth your time.
I would also recommend reaching for some mods. Not necessary, but I refuse to play without them:
1) Enhanced User Interface - adds some icons and colour coding to make game’s mechanics easier to understand.
2) Community Patch - might be a bit biased, but thanks to hard work of a wonderful folks in the community we got those lovely pack of tweaks and fixes. But being a shallow person that I am, it is a must for me due to unique icons made by @Boeroer to make skill trees a bit more exciting.
3) Deadly Deadfire (just xp!) - while the whole mode is great, I wouldn’t recommend it for first playthrough. I would, however recommend the file that just reduces XP by 25%. Due to the open nature of Deadfire it is too easy to greatly out-level available content for the vast majority of the game. While PoE1 had reputation of being perhaps to difficult, Deadfire swung the other way. The penalty to XP makes it possible to the enjoy all the content there is, without getting too ahead of the difficulty curve. The base game is still pretty easy for the most part.
