the opposite happened to me, i've beaten Pikmin 1, getting all 30 pieces in 23 days i think, there was no way i wouldn't get the second one and the 3rd one
it was great to find out how the pieces were hidden!
it's not that hard if you plan what you'll do the next stage, it's mostly strategy i think
the second one is much better i must say, you looking for a treasure, there are two playable characters and two new Pikmin colours
the best, there's no time limit!!
don't mind my username, that was more than 10 years ago, I'm a different person now, amazing how people change ^_^
