Why couldnt the Epoch go to other periods of time? The simplest answer is that it could only go to certain weak points in time. But since there seemed to be some other entity involved, the answer may simply be that they were only able to go where the entity wanted them to go.
As I recall they could go to a time +X.
The time being an exact second... the +X was how much time had passed in their life (or the person controling the gate). So if they live five hours in the past, they won't return to the exact time they left. They return to the exact time they left +5 hours.
Now if only I could remember where I found that out... apart from the fact its obvious when playing -_-
Why? If you can travel through time you can go to WHATEVER time you feel like, if you want to go to 1 second after you left your normal time period, you can.
Universal Continuity of time
The Epoch could go to specific time periods. however, time passed in all those periods at the same rate, no matter when you went to them. I believe this is to prevent the paradox of running into your past self.
The only exception was the Time Egg used to ressurect Crono, and that only let you go to a specific instant in time once.
Now that I think about it, there was also that red gate that appeared, which allowed Lucca to go back into her own past to prevent the accident that crippled her mother. Then again, it dissapeared after you used it to get then and back, so specific instant gates must be one use only...like the gate that took you to the Day of Lavos.
All I understood was the paradox part. Or at least where I knew what you were talking about.
Well the portals are understandible.
True they take you to a certain time... but they are also moving through time like anyone or anything else. That and if you come out at an exact second each time, you'd come out along with EVERYTHING ELSE that ever used it. Which in a small room isn't going to be pretty.
Not neccesarily. It could possibly split dimensons or have a failsafe so that you can't go to crowded times, and make a portal go to the closest destination.
Oh...So that's why only three people could use a portal at a time, and the rest had to stay back at the End of Time. Any time more than that many people tried to use a portal, they got rerouted to the End of Time.
Isn't that from the flash game?
