VII- I'm not exactly sure why, but I always rotated my party around, depending on what part of the story it is. Whenever Corel is part of the storyline, I always make sure to include Barret, just because it seems to be the most logical character. Or when it's near the end of Disc One; Aerith is always in my party because she's gone soon. It's self-imposed storyline parties, basically. Whenever there's no need for story (side-quests etc.) it's always been Cloud, Yuffie and Cid. I never really used Cait Sith. I get that he's an avid magic user, but I found his limit hard to use and potentially fatal.

VIII- Well, I never really used Zell often. I don't know if it's his one-sided personality or his "street fighter" style limit, but I don't know. I never really used him. The same can be said for Irvine, I found his many different shots could have been replicated by other means.

X- Finally, we can change out our main characters! I used Rikku, Wakka and Tidus normally. During main-game, I of course made certain to swap characters out for SP, but after Yunalesca my characters were split up. My bench-warmers consistently were made of Lulu (Magic can be used by others), Kimahri (Because smurf you, Kimahri) and Auron (Power superseded by Wakka eventually). Yuna is interchangeable, The sisters trio did help out lots at first, but eventually even they lost favour.

XII- Anyone remember Team BAP? Yeah, I always used Balthier, Ashe and Penelo. The bad thing with this game is that the characters aren't unique in anyway. Their a blank canvas. Because of that, it's just pure visual reasons. I didn't like Vaan's abs, and I didn't like Basch's robot walk and scruffy hair. I did like Fran, so she did sometimes make a guest appearance.

XII:RW- Penelo, because she's the only healer. Basch because his "shining ray" ability just obliterates everything. Ashe because I liked her "hastega" and "comet". Kytes because he has so many damn powerful abilities. Llyud because his "jump" ability can be put to good surprise attacks and he's very versatile and fast. Everyone else, sans Filo for her attribute reducing traps can just disappear. Especially Fran, she's just terrible.

XIII- Were fixed for most of the game, so no comment there. During most of the remainder, I used Lightning, Hope and Fang. It's just the most versatile team. Fang for attack, Hope for support and Lightning does both. It's amazing. I do use Snow and Vanille when their needed, but that's situational. Poor Sazh, I loved his character, but I did miss his battle skill.
