Just finished the game after about 20 hours (it does surprise me to see people finishing it after 40 hours or so, since I've explored a lot but couldn't go beyond 20 hours, I will have to go back and check if I may have missed a lot of stuff).
There are some definitive improvements from Age of Decadence, mechanically speaking mostly, especially about the combat. I've ran into a few pathfinding issues with my character and the team, but nothing that couldn't be easily fixed.
Beyond that, no technical issue aside from the default settings which needed to be tweaked a little bit (V-Sync, scrolling speed, horrible motion blur, stuff like that).
On the level design side, some areas like Hydroponics or The Pit were well made and very interesting to explore, while the Habitat felt a bit repetitive and bland.
While the setting had potential, much of it feels untapped... although the idea that the Ship doesn't have any windows, external monitoring equipment or lacks the ability to just send a probe or someone through an airlock to check if we're even moving feels strange, if not contrived. I'm a bit mixed about the writing and the story, in general. I haven't seen any real usefulness for the companions outside combat, they do have some questlines but it mostly revolves around revenge plots, they have few commentary and few real bonding moments : to give an example, it felt strange for Knurl to not have any dialog option to provide some more details about his life in the Heart and how they're organized there.
I feel like the moment we reach the Bridge should've been the midgame, and what we learned there should have been the trigger for a new set of conflicts, tensions and development between factions, rather than the end game.
The factions, aside from the Monks felt like flavour and I was a bit disappointed to not have much details, at the end, about the consequences of some choices (though that may be related to the ending I picked, so for now I'd nuance this affirmation).
Overall it wasn't a bad experience, but nothing impressive or very innovative either. I'm definitely interested to try another playthrough with different options this time but it was definitely not as engaging as AoD was.
