This is a very bad adaptation. You can't just put 60 hours of a jrpg into 2 volumes of manga. So much is cut out, the order of things is sometimes changed to merge separate occasions, it feels baffling for someone who played the game.
At the same time, for what it is, this is a very good adaptation. Fitting 60 hours of jrpg into 2 volumes of manga might be a fool's errand, but this somehow manages to execute that in the best way possible under the circumstances. As far as I remember, nothing important is cut, and the merged plot lines are ingenious, bordering on insane.
A very interesting read if you've already played the game and wanna see how they managed to fit all of that into 2 books. A very bad way to actually experience Tales of Berseria.
