well first of all WHY DO YOU ALREADY HAVE YOUR N-ZONE AND I DON'T??? Ah I know, because I live in Switzerland and the post is lazy, so that I always have to wait a week until I get mine
But I'm a bit puzzled... First of all, I want to say that N-Zone is normally quite reliable and not biased. You also have to know that their scores are a bit special (I think) because getting a score below 80 % means the game is not good normally, while at other sites/magazines a 7/10 is still good. But then again, a score around 90 % is still very good.
And what I'm really more interested about are the dungeons rather than the sidequests. How is the dungeon architecture? Are there difficult, clever puzzles? I read there are seven dungeons, and I think this is enough for a handheld game, so altough I usually trust N-Zone, I'll go with the score rather than the words.
