I don't know why but I was super harsh on this back on the Wii U. I was super hyped, bought the Wii U just for Pikmin, and though I liked it, never enjoyed it anywhere near as much as 2 (one of my favourite games ever made).
The QoL additions are fantastic in this, and I'm enjoying it so much more than my first time back on Wii U. The Piklopedia is amazing, I'm so happy it's back. The Side Story and Mission Mode content is fantastic as well. My impressions of it are much improved, though it still doesn't compare to 2.
I love this series, and I can't wait for 4.
