You should play Chrono Cross. Of course it's not the same! It's the sequel, not a remake or something! It takes place 15 years after the events of CT and expands (eventually) on the storyline...plus, there are cameos and "Easter egg" character mentions & such throughout. If you're a fan of the series, it's a must play.
Anyways...so you've played RD in English and stuff? Got all them whakky endings?
