Despite growing up with its successor, I didn't actually play through the original Pikmin until my late teen years. I also played it again recently, and I think both times, it held up rather well. I'm not keen to replay it over and over in close proximity as I think the developers intended - the high score element is cool, but not really my interest. However, the shortness of Pikmin does mean that coming back to replay it once in a while is rather easily afforded. It's a classic, and the cave level is my favourite.
