Because there is some confusion in the comments here, I hunted down the written portion from the magazine from the source mentioned in the link:
Pikmin 4 9998
- Dandori, which is the charm of the series, has been sublimated into play
- The quality and quantity of what you can do has been improved, but it has become easier to play
- Exploration is rich in variety and you won’t get tired of it
The 9998 refers to the 4 scores in the title of this post. I cannot verify the accuracy of this translation or verify that it was correctly transposed from the print magazine. This was translated using Google translate by me.
If the community wants or doesn’t care for Famitsu reviews, please let me know on the comments.
I’d argue that Famitsu used to be a notoriously hard reviewer… but with the online age that reputation has more or less dissolved. Perfect scores are significantly more common than they used to be.
