It said the Planet brought back Dinopolis to counter-act Chronopolis being brought back.
was that not merely because of philosphical/physical laws you have mentioned before. the planet did not think o look chronopolis is being sent back in time lets send dinopolis as well, it was just an automatic thing that occured because it would defeat many laws for it not to.
When the game actually comes out and tells me "The Planet did X" I'm inclined to beleive it. I'm not sure what laws you are referring to, unless you mean the Conservation of Time Theorem, stating no more than three people can time travel at once. And that has also been explained in another article on the main site. I believe it was the one pertaining to the Dead Sea.
About this whole side quest thing: What is the main purpose of CT? To defeat Lavos. Thats the main quest. Everything AFTER you get to the End of Time for the first time IS a side quest. You can fight Lavos right there with the bucket. Its possible to level up just fighting monsters and stuff in time periods you have already been to. But we consider EVERYTHING that happens after that part of the story.
ive already said how it is a sidequest, after you resurect crono the next step in the story is to defeat lavos, after you get to the EoT for the first time you there is a reason why you dont go straight to lavos, for one gaspar tells you not to, and secondly the story tells you not to. if you do fight lavos before you resurect crono you are going against the story, if you fight him after resureting crono your merely avoiding sub storylines.
Just because a person (in this case, the gamer) is not aware of something doesn't mean it does not exist. Just because one may chose to miss the fire side chat does not invalidate what was discussed in that scene. It just means the player is a crappy gamer who missed things.
The disappearance of Marle in 600 AD (recalling that the Grandfather Paradox does not exits in the Chrono universe)
you already did that with the intertia theory.
Except that I already said the Temporal Inertia theory has already been debunked, since by definition it still applies the Grandfather Paradox, albeit at a less-than-instant rate of effect. The theory is flawed, so it cannot be used as a counter-point. I subscribe to it because it can explain the presence of Doan at the Moonlit Parade, and I am trying to work out the flaws on my own, but so far, I have yet to succeed. It just doesn't work.
[for the existence of the gates ive always blamed it on lavos, as for where they take you to, i had a theory on that but ive forgot.[
Right, because Lavos wants to die at the hands of three kids, a frog, a cavewomn, a robot, and a pissed off wizard. That's why it created the Gates in just the exact times and places that would facilitate its own end. Good point
EDIT:
As for the planet's dream... its really hard to tell exactly what is meant by that. Assuming its responsible for various events in the Chrono universe... is it an actual being? What exactly is it trying to accomplish by setting certain things in motion? What is its ultimate goal?
The same as all sentient beings: To Live. To Survive.
