Ni No Kuni has a fun combat system and plenty of interesting monster designs. The cutscenes, especially the 2D animated ones, are a delight to watch and you are able to skip them if you have watched them already or just want to get on with the story.
The only problems I had with the game were the lack of balance between some familiars and the grinding necessary to add a new familiar to my team, however those issues were minimal compared to the enjoyment I had with the rest of the game.
