I used Crono, Marle, and Frog.. mainly because I had to use Frog cuz of the Masamune, and I think Marle and Frog had a double-tech that healed everyone completely (Cure Water, I believe).. I really wanted to use Magus, but if I switched either Marle or Frog I'd lose Cure Water...
For Chrono Cross I used Serge, Guile and Karsh, I think... I don't remember as clearly as Chrono Trigger.. I mused Guilge cuz he was strong with elements (was the stat called magic in CC?), and Karsh cuz... he looked cool and I missed out on Glenn.. I used Pip for a while cuz I read about his ability to morph, and I expected him to get stronger with each form, not that each form was a different innate element.. I used Serge, Pip, and Guile up to Fort Dragonia, then I guess I just dropped getting Pip back when I got Guile back... I recently played most of the game again (up to the point where I can go fight the TD if I want) and my party was Serge, Glenn, and Kid.. I like that party better
Eriol, isn't that the guy from CCS? I never saw past episode 12 or so as CCS, though I saw most of the episodes as Cardcaptors... I would've completely forgot about him if he werent in the second movie..
