I hate when people say "Chrono Cross wasn't meant to be a sequel!" when the plot makes absolutely no sense without Trigger, and even then it's confusing. Instead of standing by Cross's merits, they make stuff up that makes no sense, and then go back on it when people complain about what Cross did as a follow-up by saying "it's the sequel, deal with it".
Enjoy the scenery, music, battle system, atmosphere, any of the things it did RIGHT... but know that when the story isn't convoluted, it's depressing.
