This is a fun little thread, reminds that I should finally finish my FFIII one...

Anyway, go with Lucca. Marle is kind of dead weight and Robo is one of the more well-rounded characters.

I love most of the cast to be honest. Frog is actually one of my favorites. My final team is Crono, Frog, and one person you haven't met yet.

Also Robo's theme is probably my favorite character them in the game.

Also, I can share this since you've met everyone!
