I can see why people think this is the best or worst Dusk game. Its synthesis is much weaker than it was in Escha and Logy, with now there being a stronger focus on exploration. I only felt satisfied playing around with it towards the end, but it doesn't allow you as much freedom as it did before. They also dulled the difficulty too much and simplified the combat by removing the positional system. It was actually TOO easy.
However, everywhere else, I think it does a great job of merging the strengths of the past two games while having a story with stakes. It has the best atmosphere, having the adventure of Ayesha and the homey town feeling of E&L. The story ties all the loose themes and character arcs in a way that stays true to its slice-of-life approach while being more serious than it has ever been. The only complaint I have about the writing is the way the Shallies' relationship could have used more time to bond like Escha and Logy. But, it's not narrative-breaking and it has the best supporting cast to make up for this.
Overall, I think despite having a story with stakes and finality, it ended up being the least stressful experience in the trilogy. In many ways, it took a couple of steps back but landed gracefully.

Third entry in the Dusk series, probably my favorite overall. Crafting mechanics are just as addicting as Escha to Logy, with a new means to attach skills to items added on top. Combat did away with positioning around the enemy for benefits, but instead party skills have a lot more interesting mechanics to them with some unique time cards, buffs, and level manipulation. Music got upgraded, the best soundtrack of the three imo. I enjoyed the cast of characters and the overall plot of this one more than Escha, and it does a good job of tying in characters and story from the first two games without them overshadowing the story of the Shallies. The Dusk gets a lot more focus this time around, and because of that it still can't quite match the vibes that came from it being so out of focus in Ayesha, but it gets closer than Escha did and the exploration of it is still interesting. Shallie makes a return to the very imagined locales of Ayesha that I was missing in Escha as well. The ending still leaves room to explore this world more, but it does a good job tying up the stories and makes a nice conclusion to the trilogy
