The Famitsu 40/40 has lost some of its lustre in recent times. Since 1998, the magazine has awarded nine perfect scores, but three have come in 2008, including one for Super Smash Bros. Brawl.
However, even we found the latest game to receive the honor surprising. 428: The World Doesn't Change Even So is a "visual novel," a graphical text adventure from roguelike kings Chunsoft that keeps player interaction to a minimum. In other words, it's very unlike any other game to receive a flawless Famitsu grade. In fact, it's unlike most other games, period.
We haven't posted a great deal about 428. That's not because we don't find it interesting -- we definitely do. It's because, as Alisha has noted, a game of its ilk is almost entirely impenetrable to our western eyes. Suffice to say, it has now been instantly promoted from "intriguing curio" to "must-own import." Not that a release outside Japan will ever happen.
