I disagree with people that say that this is not a game for the very young. My 6 year old daughter has been glued to it for the last 2 days and is solving lots of puzzles on her own (admittedly some have been lucky guesses but lots of them are very accessible and many others I can explain the logic behind to her). Even if it was just for the amount of reading she's been doing over the weekend, this is a winner. Not much of the reading material she brings home from school elicits the number of WOWS and OHHS that Professor Layton does and she is utterly captivated by the enigmatic storyline and the many quirky characters. Which doesn't mean that this is a substitute for books... but it's nonetheless a joy to read together and work on the puzzles with your child, and I can't recommend it enough.
From the point of view of an adult, the puzzles feel much easier this time and there is a deja vu sense to it as Pandora's box is structured in the same way as the first game. Still, with all this in mind, I would buy it again. There is so much to be enjoyed in the design, the beautiful detail, the delicious mysteries, it's all a treat to the senses as much as a bit of a brain shake... so scrumptious, you just want to eat this game. More, please.
