Technically all of the games take place in a new timeline, though (CT=Entity's changes, RD=w/e, CC=Serge not dead). To me, it's the standard of the series, really...And RD has Magus in your "party"...I know that's not "Crono & Co.", but it's part of that bunch anyways, which is slightly more than you can say for CC, though Crono & Co. sort of cameo in CC...*shrugs*
