How would you guys compare this to symphonia, abyss, xillia and vesperia?
I honestly couldn't get that into Symphonia, though I did respect its ambitious storytelling that I think Abyss exceeded. The larger cast made it much harder to get into the characters as well as I did with Berseria's, and Berseria's main characters were (to me) the strongest the series ever offered. It probably didn't help that I played Symphonia far later than Abyss, Vesperia, and Xillia. Overall I'd say Berseria is a much more focused story than Symphonia and has better combat (I felt Symphonia's combat was just too slow).
Tales of the Abyss is/was my favorite in the series (until this game), the usage of the God Generals and Van were something I felt most of the rest of the series was lacking (strong, menacing but deep antagonists). The antagonists in this game reminded me of this, with the unique twist of being on opposite sides that the Tales games usually are, and that was only a big plus for my opinion. I put this game on the same level with Abyss, where one game lacks the other picks up.
I liked Vesperia's skill system for having more impactful skills but I also hated how limited the choices were to equip the learned skills (due to skill point restrictions). Berseria does away with the skill limits, but at the cost of less amazing skills. Vesperia has prettier and more imaginative dungeons (overall) but I felt many were extremely tedious, far more than Berseria's worst dungeons. I also really hated Karol, I "got" his character but just didn't like him. Vesperia is the only game in the series I actually chose to play someone other than the main character, too. I liked Repede more than Yuri, but I had way more fun playing as Velvet than any other main character in the series.
For Xillia, I am not sure why but this is the only game in the series I was "done" with after finishing both stories, I felt it just didn't have a very good story (far weaker than Vesperia's 3rd act). Xillia's dual story system was pretty poorly executed. Too much of the story was still shared between Jude and Milla, and the scenes that were different I felt could have been seamlessly integrated the same way the way Asch's parts in Abyss were. I did like the cast quite a bit, but I think Berseria's was overall stronger. The combat in both games felt pretty mindless to me (Graces still is the best for this imo, and Berseria's is closer to Graces), but I did appreciate some of Berseria's Break Soul and guard systems.
With all the pros and cons of the game compared to others, my ranking goes more like, Berseria = Abyss > Vesperia > Symphonia > Xillia
