I saw your post and immediately invited you to
the Pikmin social group, not realizing that you were already a member, haha. Woops.
Pikmin 3 was pretty good, yeah. I'd like to play through the story again sometime now that I have a somewhat better handle on the controls. I really enjoy Pikmin 1 too. While it's pretty simple, I think it can be fun to replay it to try to beat it in fewer days or with fewer Pikmin casualties than the last time you cleared it. I'm not one of the pros who can beat it in 9 days or 0 deaths and probably never will be, but I like the challenge of trying to beat my high scores.
Pikmin 2 is still my favorite though, mostly because I actually like the caves and the bulbmin a bunch, and feel like two leaders is a happy medium as far as multitasking goes. I'm also a fan of the suit upgrades and hope they make an appearance in 4.
