Chrono Cross, is not a direct sequel to Chrono Trigger, as Takashi Tokita, mentoined a Chrono Trigger 2 in 2003. It is believed that Chrono Break was going to be a sequel... but that's vapourware...
Hmm, never spent much time with CC...I'll have to look into that. What the hell is vapourware btw..?? Nevermind, I just googled it...you just introduced me to a new term my man...Oh and it appears to be spelt "vaporware", but thanks anyway
