How is the video game?

How long is it?
Like Ni No Kuni, Wrath of the White Witch is very long, Minecraft is endless, and [insert short video game here] is a decent amount of time, so It makes anda happy, but anda don't get bored of it

Do anda have to read the buku atau watch the movie to play it, atau can anda just jump right into the game and know what's going on?

Is it true that it's on the Xbox 360?

and can anda be any age to play it?

I'm just wondering because my kegemaran YouTuber is 23 years old, but he's pretty childish (in a fantastic way) and he asked the veiwers what video game he should do a let's play series on next. I would like to see him do The Spiderwick Chronicles, but I'm not sure if he has ever read the buku atau watched the movie yet.

(btw, his YouTube channel is Stampylonghead. I suggest anda check him out! He's awesome!)
