Summary: If you have a DS and enjoy role playing then you should have the Dragon Quest games. Unfortunately number IV which I think is the best of them all, had the vast majority of its dialogue removed. The fan outcry was obviously heard because that was restored for V and VI. This game does a twist on some typical features you're familiar with in these settings, the dream/real world is similar to but different enough from the Link to the Past's Light/Dark world.
Summary: Honestly, I haven't played this yet because I'm working on Dragon Quest 5 but I know I'll be giving it a five star. I love the Dragon Quest series and have played and beaten 1,2,3,4, and 8. They are all similar in terms of gameplay and each have their own unique story. If you like RPG's then this is one of the best series ever.
