If thats what you've been trying to say then I disagree more fiercely then before. CC is the sequel to Chrono Trigger. Just by knowing facts about the game you can see how it doesn't add up at all.

Ultimecia is a crazed loon seeking power where Schala is a young women seeking refrence from her mother, who was far more like Ultimecia then she ever was.
Also the ideas of time travel are completely different. If FFVIII and CC where just different ways of getting from point A to point B then they laws of nature should be the same, and they aren't. In FFVIII time travel cannot be done without some ildefined power and not even that can bring bodies back in time, only minds (whatever Ellone had I don't quite remember), but in CT (I'm going to say CT because I know more about it, and CC being its sequel has the same game laws) time travel can be done by anyone who has the proper piece of technology.
