This is a really cool strategy type game. You are a bunch of visitors from outer space, land on a planet where you proceed to enslave the locals and extract the natural resources to bring away with your ship.
Jokes aside, it's a bit more childlike but definitely an entertaining and fairly complex game. The graphics are absolutely beautiful, I was impressed with the performance of the Switch. And there is a whole bunch of content in terms of monsters, Pikmin, dungeons etc.
There are only a few things I didn't like. First of all the story is a bit lame. Without spoiling it, the "villain" of the game has no reason why he does any of the things he does. He is just a person with the brain of a 5 year old apparently. Lazy writing.
Also they retconned the stories from the previous games for no reason.
I also didn't like so much the point of the treasures. In previous games you wanted to find the treasures to make money or to survive. In this game they don't really have a purpose, you just collect the things for the sake of collecting them.
The dog is cool but I don't like how all 100 Pikmin can ride on him because that makes the whole gameplay too easy.
Still overall a very good game and definitely worth playing.
