Dude, that guy is fucking stupid. I didn't even bother to read all of his new theories that Hopeful Death posted. First off, when I read the first one, it went over my head. I don't even remember it because it was ludicrous.
For one, on the back of the CD case for Chrono Cross, it says that it's a sequel to Chrono Trigger.
Chrono Cross was the result of Lavos' demise in 1999 A.D. so there would be a peaceful future and for there to be a Time Crash to occur. And because of that, El Nido exists too so there could be a Chrono Cross story. So I don't know what that guy is talking about when he is trying to explain how CC isn't the sequel to CT. It was Crono and company's actions that eventually had the events in Chrono Cross occur. Think about it; Crono and co. kills Lavos, future is peaceful, Frozen Flame is discovered and is researched upon in Chronopolis, Frozen Flame is activated and the Time Crash occurs, Chronopolis is sent back in time to 7600 B.C. because it was hurled 10,000 years into the past, the Planet sends Dinopolis back from another dimension (Reptite's Dimension, where the Reptites killed off the humans and shit), they battle, Chronopolis wins, Fate uses the power of the Frozen Flame to break down the Dragon God into six lesser entity's, Fate seals them away and creates El Nido among other things (Records of Fate, etc), and the people of Chronopolis have their memories erased and they start new lives in the artificial archipelago that is now El Nido, and in 1020 A.D. we have the Chrono Cross story. Now, if any of this information is wrong then please feel free to correct me. My whole point was that CC is a sequel to CT because the events in CC occurred because of the actions of Crono and company in CT.
Radical Dreamers is the sequel to Chrono Trigger, and Chrono Cross is the remake of said sequel.
What more can we all say to obviously further prove that this person is full of shit when he says that CC is not a sequel to CT? I rest my case.
About the Son of Sun:
Well, when you think about it, there really is no justification for Crono and company's actions to just go and kill the Son of Sun. He didn't do anything to them except fight back when you initiate battle with him, and that isn't a bad thing either. You could say that the Moonstone, once the Sunstone, belonged in Zeal. However, Zeal fell and they are long gone, and this was in the bleak future, way after that. Nobody owned that stone anymore. You could say that they needed that stone, to recharge it, and make weapons to help Crono and company in their quest to defeat Lavos, a great Evil that must be stopped. However, the Son of Sun didn't have to die. So you do have a point there.
