Apparently, Famitsu gave Kingdom Hearts 3D a 38/40. For the record, RE: Revelations got a 39/40 and Kid Icarus: Uprising got a perfect 40. Kingdom Hearts 2 got a 39, Birth by Sleep got a 37, and 358/2 Days got a 36.
The game is due to be released in a bit over a week from now, and is expected to debut at the top of the Japanese charts.
