Frequently asked

How much is Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy worth on the Nintendo 3DS?

A complete copy sells for about $12 in PAL (EU, UK, Australia). Most go for $8 to $17. A sealed copy sells for $13 to $25.

How do I tell which copy I have?

Look at the rating badge on the front of the box.

An ESRB box, black and white with a letter in it, means a North American copy. Canadian copies have the same front with a bilingual back.
A PEGI square with the age in it means a European copy. France had a box of its own for the same cartridge.
A USK square (ab 6, 12, 16 or 18) means a German copy. Germany rates games itself instead of using PEGI.
