In Level-5's homeland of Japan, the top-hat wearing sleuth Professor Layton is well past his originally planned trilogy, but North American gamers have only recently caught up to the second game in the franchise. According to Level-5 president and CEO Akihiro Hino, a combination of localizing the game's puzzles and images and giving each title enough room to breathe at retail are contributing factors to Layton's slow release schedule Stateside. "We want to let each title have time to perform on the market before releasing the next game," Hino told Wired.

As for the recently released sequel Professor Layton and the Diabolical Box, Hino estimates the game features "roughly double" the amount of data than the first. Not only is Layton's new tea-sipping adventure bigger, but it makes more sense contextually. "One lesson we learned from the first title is that some puzzles seemed irrelevant to the storyline," Hino said, noting the Professor's second outing actually works the puzzles into the game's story to give them a purpose. "For instance, you may have to solve a puzzle about a key in order to enter a locked chamber."
