I played through the demo yesterday, and loved it. I've only played the first Pikmin on Gamecube (although I do have an unplayed New Play Control Pikmin 2 for Wii as well), and I forgot how charming it is. It's my first proper exposure to Rock Pikmin and I love them. I also love how Alph and Brittany have distinct personalities that come out in their journal entries about stuff they've discovered. Will definitely pick this up sometime soon.
