it's a very good game, I think that if I did not check the marketing, I would have liked it even more though
it feels more like a "filler" than the rest, the plot does not advance but still we conclude some arcs (char etc..)
On side content levels
it has the best side quests/bonding events in the series for me.

The final boss is the best in the serie and it is not even close and the end with the DLC just got me hyped for the Final chapter and I think this game is the best setup for it

I still think that chapter 3 is poorly executed : the plot point is good but should have been done differently
