Chrono Cross was a great game, there's just something about Radical Dreamers that overall I liked more. Which is odd, since I liked a lot of things about the timeline in Chrono Cross more - the nature of the frozen flame; the fact that (SPOILER)in the Radical Dreamers timeline Crono is almost certainly dead, while in the Chrono Cross timeline Crono is almost certainly alive, or at the very least he and Marle survived the fall of Guardia; Fate was a villian I absolutely hated (the good, getting into the story kind of hated); I liked how Kid and Schala were pretty much separate individuals in Chrono Cross without them eliminating their link; and several other things.

Maybe it was the ending.
