The game will have been out in Japan for nearly two years by its October 17 release in the US, so this isn't exactly a new game. Nintendo has made a little tweak to the North American version of the game, however, which will shorten the wait to play one of the title's more intriguing aspects. The bonus game, Professor Layton's London Life, will be available from the very start instead of being unlocked upon completion of the main story.
London Life is an RPG developed by Brownie Brown, one of the three teams behind Mother 3, and has the player performing quests for various Layton characters in London. The game is said to have a running time of about 100 hours, so it's a huge bit of content that sounds pretty cool. I'd probably be pretty eager to try out something different after a few frustrating puzzles from the main game and I think it's neat that this will be unlocked from the start.
