I regretted not having access to all the dormitories as in the first at the same time as and when I realized it was very well because in the end this version is not heated and so on discover other parts of Hogwarts and its surroundings (station, observatory, pre bacon, etc) and in the end everything perfectly coincides with the history all very true but I did not understand immediately since I have really caught the last Potter I have neither read nor seen them but in the end it did not bother me ...
So here I finished it 100% easier than the first and I enjoyed those long moments playing it !!!
I recommend, just to complete your saga, you will not regret it ...
