The world itself is certainly nothing similar though. At the rate of an inch a year, two thousand years isn't really enough to move around an entire world.
Yes, but the combination of two worlds is. Another thing is that in a libary in one of the castles (in Phantasia), it mentions the two moons, which have the same names as the two worlds of Symphonia. There's a lot more on wikipedia about this sort of thing.
Anyways, I've only played ToS... So.... Yeahhhhhh. That sort of says my vote right there.
