If Nintendo released Professor Layton's London Life as a standalone DS game, we'd be totally into it. As this trailer shows, the Brownie Brown-developed RPG offers an alternate take on the Layton world, with sprite-based characters, a top-down, explorable London, and a purported 100 hours of gameplay.

We're glad Nintendo didn't find out we felt that way, because London Life is totally thrown in as a bonus with Professor Layton and the Last Specter. We ... hope Nintendo's already printed the carts, now that we've said that.
