Japanese gaming magazine Famitsu has revealed the top selling PlayStation 4 software in Japan. On the second spot you can see Metal Gear Solid V: Ground Zeroes, having sold 150970 copies.

The game came out in March for Xbox 360, PlayStation 3 and PlayStation 4, and in September for Xbox One, so take into account the total sales are higher.
For the record: Knack came bundled with the PlayStation 4 sold at launch, which explains why it takes the top spot. So to be exact, Ground Zeroes is the best selling stand alone PS4 game (note that a bundle including GZ did exist in Japan, but this was a specific offer that did not ‘skew’ the sales charts).
