When I first played Pikmin 1 I got really frustrated because the days were too short for me to actually accomplish anything worthwhile.
It seems the lengh of the days was extended in Pikmin 2 but I never played it, wish I had though because it looks and plays way better than the first.
If I get a Wii U then I'll probably be picking this up as well but I'll wait and see if anything more about it comes out at TGS and Leipzig gamescon.
