I never finished VI, because I got bored, but I'm right there. I think I just want to do all the remaining sidequests first. I never finished I, or III (but I never got far in III), or IV. I nevcer started II.
I stopped playing XII for no reason.
All the rest I've beaten (V, VII, VIII, IX, X, T, and TA).
To beat VIII, it takes some work. When I started a new game, I traded junctions alot in order tog ive characters level up bonuses that would make them into what I wanted them to be. So I knew that Rinoa has one of the best limit breaks so I made her into a physical powerhouse and gave her lots of vitality and spirit. I made Zell into a fighter with some decent magic. Squall was a powerhouse (but it was difficult since he's in every battle and can't be given all the GFs needed to boost his stats). Selphie and Irvine were balanced Redmage types, and Quistis was my main mage.
They're all good characters if you work them right. Irvine's Pulsar Ammo and Piercing Ammo can do amazing amounts of damage, Selphie's reels will do a lot of good work if you hit 'O' to redo them if you don't like what you got (like her Full Cure will heal you even if you're invincible). Quistis is good for her Might Guard which can give Regen, Float, Wall,
and Aura, and for Shockwave Pulsar which can do over 9999. Rinoa's Invincible Moon and Wishing Star are geat for support and attack, respectively and probably saved me more than anything, and Squall's Lionheart is a great offensive. I don't use Zell's limit so much, so I use him for summoning and upkeep of the rest of the team. I load him with the powerful GF's like Eden.
So you can definitely ensure that even if Ultimecia picks a crappy starting team that you can hold your own. The key is using Aura
