Curiosity, but when one takes the Bucket at the End of Time aren't there red sparkles of something that accompany the teleportation? Might this be another instance of the Red Gate effect (as where it drops you out does not correlate to any other gate location)?
Quick question(slightly Off-Topic); at Chronopolis has time been decelerated as the area seems immaculate time-wise?
Actually, time (4-D) has not been "decelerated" as creatures from Chronopolis are able to still interact with Serge & Squad. We might suppose that Serge and the others are immune from the curious time effects of Chronopolis, having entered it, but those who were already there should have been "time decelerated" as well, if the rest of the place was. However, Time Error (5-D) might have been, as the "gate" effect of entering the area does not seem to match the time spent. That is, by Time Error entering Chronopolis should take one 13020 years into the future of when this effect was created (2400, on the exit end). However, it looks mostly like a comparatively short period of time has passed (maybe just a few hundred years?)
To be more specific shouldn't the 2300AD gate be green only AFTER you unlock Newgame+. In the end the gate is still blue but they make not that its not the destroyed 2300AD anymore.
Actually, that is a very good point. The Blue Gate at the end of the Game (through which everyone goes to their respective timelines) is notably blue. Perhaps this is just a link to the End of Time, at this point, from which the various characters then go to their various timelines. However, if not, then it is dumping Robo, Doan, Ayla, Kino, and Magus in 600 AD again.
But this leads to a more interesting thought: the Doan Paradox. Assuming that this singular gate is supposed to exit into the various respective timelines like it is implied it does, then the blueness of the gate indicates that Doan and Robo are traveling to the ideal future (thus, sucks to be Doan because his entire life remains in the ruined future). If they were traveling to the ruined future, then this should be green under the current discussion's theory (as the ruined future should have been discarded as soon as Lavos was defeated).
However, given the Entity's power over both time and dimensions (as displayed from it pulling Dinopolis into the Keystone dimension/timeline), might it be that the Entity was actually preventing the ruined future from being discarded? Indeed, the Entity already seems to be considerate of Chrono and Co as the gates are still active even after Lavos has been defeated (the only reason for the Entity to keep them open at that point if for Magus, Frog, Robo, and Ayla to return to their own time periods, it seems). By allowing the various characters to get to their respective time periods first, might they then be effected by the rewrite of time that would happen once the entity stopped holding those changes back?
This would result in a much less contaminated timeline (like Frog potentially having armor made from metals that shouldn't exist in 600 AD). Of course, by TTI the various individuals would step from the gate in their pre-change form, but if they are in that timeline when the changes happen, wouldn't they still be affected? That is, they'd step from the gate pre-change but immediately be altered to the new timeline.
If so, then that would seemingly resolve a nasty component of the Doan Paradox and explain why that gate is not Green (as this theory would indicate it should be, if it connects to the ruined future).
Then, in New Game + we might consider that the 2300 AD gate is blue specifically because the Green Gate exists; Lavos is connected from the DBT to the real world, and thus his influence might be renewed (and so even though the ruined future should be discarded, as long as the Green Gate exists that ruined future still exists as well).
Anywho, just a lot of somewhat scattered thoughts.
