Developer: Nintendo EPD
The Pikmin series always felt a little un-Nintendo-like to me. I mean, you play as a little astronaut who can't jump, even though he's named after Mario, you don't have direct control of the Pikmin, and it has realistic graphics reminiscent of a science book. It's the polar opposite of Mario and everything else Nintendo makes. Pikmin 4 is still that game it was on GameCube at its core, but it's been modernized and refined into something more people can get into.
If I were to describe Pikmin to a newcomer, I'd say it's something between a real-time strategy game and playing a pet class, like a Necromancer, in Diablo. Your character can't do much, but they can command an army of Pikmin to attack enemies, collect resources, build bridges, and break walls much like units in an RTS. You start off with a few Pikmin and grow more as they take resources back to their nest, the Onion. Yes, grow. They're plant creatures.
I was honestly very surprised by Pikmin 4. I've played all the others and liked them, but I wasn't expecting to love this one so much. It's by far the best Pikmin game. It just has so much content, great challenges, beautiful graphics, and great new additions, like Oatchi, the new modes, ice Pikmin, and the hub area. I didn't even talk about multiplayer. It's local only, so I didn't get to play against anyone, but you can play against the computer, at least. Regardless, Pikmin 4 is one of the best games I've played this year. I can't recommend it enough.
