Golden and Mop: Play the game before deciding that the time limit will ruin your game.
Like we have said over and over again, the experience will differ from person to person and hell, the time limit might not be that big of a problem.
Mop: Read back what I said on the NPC Pikmin thread, you DON'T NEED to restart days.
In my honest opinion, I think both Golden and Mop are looking for excuses to not play the game because they fear the time limit WILL ruin the game.
Its understandable. Whenever a new experience rolls by it can be intimidating and start to wonder the worst. Hell, when I was younger I FEARED RPGs because the gameplay and the stats intimidating me, and I thought I would never get it or even enjoy them. But then I played Super Mario RPG, which is a basic RPG, and once I understood the concept of RPGs I enjoyed them and I stopped fearing them.
Not to sound condescending, but my nephew was 7 years old when he first played Pikmin. He was very young, still learning to play games and couldn't speak English. Yet, he understood the game, was NOT scared by the time limit and beat the game several times, even before the days were up. And he barely asked for my help.
If a young kid with no English skills could play Pikmin and enjoy it despite the time limit I think the two of you, experienced videogame playing adults, could have no problem. Just stop looking for excuses and play it.
