Perhaps if we define our terms, this tired issue can be put to rest:
sequel (NOUN)
1. Something that follows; a continuation. [/list:u]
2. A literary, dramatic, or cinematic work whose narrative continues that of a preexisting work. [/list:u]
3. A result or consequence. See Synonyms at
effect. [/list:u]
Armed with this knowledge, lets see if CC measures up to the definition of a sequel.
Q: Is Chrono Cross a continuation (ie, Something that follows) Chrono Trigger?
A: Yes. It is revealed through the course if the game that several storylines from CT are continued, and in some cases, completed. Such as the final fate of Lucca Ashtear and Robo. The rise of Porre as a global power, and the subsequent fall of Guardia. And let us not forget that the Schala question, THE single greatest unresolved plot point in the first game, is finally answered.
Q: Does the narrative of CC continue that of a preexisting work (in this case, Chrono Trigger)?
A Yes. "Come to me, the Assassin of Time... The Chrono Trigger!" Ring a bell? Though the story development of CC is admittedly inferior (in my opinion) to that of CT, the fact remains that it does continues the story began in the first game. Don’t believe me? Who found Kid again? Lucca. Who locked out FATE's access to the Frozen Falme? Robo. Who orchestrated the entire game? Belthasar . Characters created and established in CT, who actions continue and affect CC.
Need something more concrete? How about something made of Dreamstone? Like the Masamune, perhaps? It story begins in Zeal and winds all the way through history, to eventually becoming one of Serge's most powerful weapons (i never bothered forge the Spectra Swallow myself... once i got the Mastermune I was like "why bother?") From Ruby Knife to Holy Sword to Ultimate in Evil to the Grand Dream of the Arbiter. What more proof of story continuation do you need?
Q: Is Chrono Cross a result or consequence of Chrono Trigger?
A: You can answer this yourself. Just load up you last CT file, hop into the Epoch, and go flying around looking for El Nido. Go ahead. I'll wait.
.....
Cant find it, can you? That’s because
it doesn’t exits until the moment Chrono and Co kill Lavos. Untill the future is saved in CT, there is no fantastic future society for Belthasar to wind up in and plan Project Kid. There is no reason for Lavos to drag Chronopolis into the past, no reason for the Planet to do the same for Dinopolis, no great 'Polis Wars, no El Nido Terraforming project, and hence NONE OF THE 40+ CC CHARATERS, NO DRAGONS, NO TEAR OF LOVE/HATE, NO CHRONO CROSS, ETC, ETC ETC. Maybe the Dragoons would still be around and possibly Norris, and maybe Starky, but that's about it. But Starky would crash into empty ocean and die, and the Dragoons and Norris would have never left Porre.
Now, in the name of the Entity, let this asinine question die.
