I completed the game ^_^ I did contemplate going for the platinum trophy but honestly the last section of the game I raced through as I was getting a bit worn down by it, it is a large game especially if you are doing everything!
The side quests are stories in their own I think but they felt that broken up as they were split between chapters if you like that they all got a bit lost, i.e. by the time I got to Lostwings ending I had forgotten what was going on there.
The battles looked fantastic throughout and the story is much better than the last few games, you can certainly see the Game of thrones influence. It does currently stand as my game of the year but I feel like there has not been much to fight for the spot anyway as yet this year. Maybe when Baldurs Gate is released it could all change.
