I love
Pikmin 2, but
Pikmin is a much better strategy game. The 30 day limit means that you have to effectively use your time. If I don't collect anything on a day in 2? Not a big deal; there's always tomorrow. In 1? If that wasn't intentional I'm retrying that day. Losing a bunch of pikmin also hurts a lot more when you don't necessarily have the time to spare to grow more.
Not having purple pikmin means that you can't just stun/poison everything and generally have to think about how to deal with tougher enemies. The emperor bulblax is a major threat in the first game and just rushing in will get you killed. In the second game, it's simple to kill him before he's even gotten a chance to attack. There are some pretty great bosses in 2, but a lot of the regular enemies stop being a threat when you have the ability to stun enemies as often as you want without consequence.
Also, the whole 'collect the globe in Awakening Wood, get yellows in Perplexing Pool, return to Awakening Wood to get blues and clear the area, return to Perplexing Pool to clear area' business in
Pikmin 2 is kind of weird. It effectively splits both areas into two sections, which isn't necessarily bad but can be kind of annoying since it significantly restricts what you can do in both areas on your first visit. The first game only has that problem in Forest of Hope, although it's still possible to clear that area without blues
if you're insane.
Pikmin 2 added some really nice features and I actually prefer it to
Pikmin, but I can completely understand why someone might like the first one more.
@Allegro:
Xenoblade is number two? I need to find time to play games again; I'm only a couple hours in.
gonk Wind Waker is easily the Zelda I feel most mixed on. On the one hand, most of it is fantastic and I would feel okay calling it my second or third favorite Zelda game if that was all I was basing it on. On the other hand, it has a few screwups that all manage to be spectacularly bad. I don't regret finishing the game, but I'm not entirely sure how I managed to not drop it at some of the lowest points. I guess I'll give it points for never being mediocre and leave it at that.
