@mightyduck: Cross and Trigger have really different focuses. Chrono Trigger has a core party of around 6 party members who have fairly fleshed our stories and get extra sidequests at the end of the game to further build upon those.
Chrono Cross has something like over 40 playable party members without a major focus on anyone branching out of the real few key characters. Also a weird thing about this large amount of party members is that your starting party from the very beginning of the game has a random 3rd person every time you start a game. So clearly not many of the characters are heavily plot relevant.
Chrono Trigger is a classic that still holds up. The SNES or DS version are the way to go though, the PSX version, which is what the Vita uses, has some pretty insane load times.
