Imagine being on a very strict diet for a VERY VERY VERY long time... while you have been craving a burger all the time.
Then.... you have the best damn juicy and delicious burger you ever tested in a VERY VERY VERY long time!
This how playing Ni No Kuni feels.... it's THAT good.
Clarification please, does this mean you've been on an RPG drought and Ni No Kuni is fulfilling the craving or that the first 4 hours were slow and now you're getting to the meaty portion?
