How? A small cast of lovable, but interesting characters? Nope, 44 cut outs with paper thin development. An interesting story spanning multiple timelines where your actions in one can drastically change the others? Nope, interesting enemies and villains? Nein. Where and how does CC "fit" in the "Chrono" universe? It mentions the original characters only briefly for what amounts to mere seconds of total playtime. The mishandling of Guile is yet another travesty. You have to take it on good faith that a game we didn't even get here is the real recollection of Guile because the creators of CC were not capable of pulling it off right and even admitted to it being too hard. Without Radical Dreamers to curb the tide of ineptitude, the crimes CC commits against the Chrono-verse are worse than fan fiction.
It's not a good sequel. That is the problem. It hardly matters what it does with the story, because the people who made it weren't competent enough to pull off a multi-faceted story with complex characters and motivations. That's what makes it a terrible sequel. Not a bad game, certainly a bad sequel. Chrono Trigger is better when Chrono Cross doesn't exist. That's makes it quintessentially a bad sequel.
People who argue that Cross is good are arguing that Dalton was one of the most important characters in CT with the power to change the course of history. Absurd, he was barely worthy of mention. Mere moments of mention in CT, translates to the catalyst of all change and arguably one of the most important characters in CC. Get out of here. They should've never made a sequel to a game designed by a literal dream team. Of course it was going to be a shallow successor.
Once again you are proving you never even played Chrono Cross.
Dalton? Dalton is never mentioned in Cross. Not once. And his actions are pretty much irrelevant to Cross' plot. The fall of the Kingdom of Guardia is mentioned what, once? And just barely. Hell, it is not even directly referenced as a fall. What exactly are you talking about? Dalton was the catalyst of pretty much NOTHING in Cross. The whole game revolves around Schala, Lavos and Belthasar. Where are you getting Dalton from?
