Pikmin is one of those series that probably wouldn’t still exist under a different banner. It’s one of Shigeru Miyamoto’s babies, an idea he fostered by playing in the wilderness as a child. One he’s going to see through until the end.
I didn’t love it as much as Miyamoto — that is until Pikmin 3. After years of casually playing the series I finally “got” it after a few multiplayer sessions with my wife, and I still play its Bingo mode to this day.
If it hasn’t clicked for you yet, Hey! Pikmin likely won’t change your mind. Unless you like amazingly cute things.
