sounds like a low-budget pokemon ripoff lol
this is nothing close to Pokemon no you do not run around a capture enemies and train them
what happens in this game is you a
space captin who is on a mission (frogot what it was its been a wile since i played)
so your in the middle of space and you come in collision with a asteriod and it damages you ship and sets you on a crash course to a nearby planet later you find these oddlooking aliens that are 1in. tall (like you) later they are called pikmin and they help you to recollect you ship parts before you run out of oxygen yo have a storage of 31 days worth of oxygen the enemies pervent you from getting your parts by eating the pikmin later the are alternate ending depending if you get all the parts or not
Win:
you sadly say good bye to the pikmin that you grow a connection with and go home
Lose:
you stay on the plant and some how have enought oxygen to live with the pikmin
