Square Enix has launched the official European website of Dragon Quest Monsters: Joker, which is filled with information and new media from the game, such new screenshots and a trailer.
If you are still unsure what this game is about, here's a short description of the story taken from Square Enix's press release:
"Welcome to Green Bays, a cluster of mysterious islands that sparkle like jewels in the shimmering ocean! But travellers beware! The islands are not as peaceful as they seem, for they teem with a multitude of monsters both great and small. Green Bays is also home to the famous Monster Scout Challenge. This renowned contest, held once every few years, determines who will be crowned the world's greatest scout. The challenge is organised by the Monster Scout Organisation, whose headquarters are located on Domus Isle, which lies at the centre of the archipelago.
Now a new challenge is about to begin, and the crème de la crème of the scouting world are converging on the islands… It is time for you to begin your quest to become the greatest monster scout in Green Bays, and in history!"
