I don't care about the score, but it's missing a lot of details. No talk about the battle card system, the Amiibo functionality, the Lakitu Centre with exclusive unlockables from completely challenges, the Trio attacks with Paper Mario, Paper Mario having his own health system, the skippable tutorials and fast-forwarding, etc.
I'm about 14 hours in, for what it's lacking in story it makes up for with improvements to the battle system and overall pacing.
