Regarding the Ending (Spoilers)
I beat the game for the first time tonight.
I managed to send both my parties down the chandelier- if there is a way to get them back up, I haven't found it. As a result, I went in to Ultimeca without GFs, items, or a save past the entrance.
Also, I approached with the party I wanted to finish with, Squall, Riona, and Quistis. I did not anticipate the rest of my (unequipped) party showing up, and Ultimeca deciding who to fight.
I did get somewhat lucky- Quistis, Riona, and Irvine were selected, meaning I had two equipped characters. I was able to keep the three on their feet for the most part, though Irvine needed life spells from time to time- however, his pulse ammo was very useful (I hadn't tried it yet).
Eventually, Irvine went down and disappeared into time. Squall took his place, and Ultimeca's griever hybrid form died. I thought I won, and then that final form rose up. When she died again, I didn't trust it until the ending started. (At which point I was glad to find Irvine wasn't perma-dead.)
That ending was mean. I couldn't concentrate on half of it because I didn't know if Squall died! I did enjoy it however, it was much more comprehensive than VII's.
I was suprised Seifer survived. That little clip with Fujin and Rajin was nice, though I wonder if he suffered any repricussions for, you know, trying to bring about the end of the world and what-have-you.
I was worried during the credits that Squall's fate would simply not be revealed. Now that I know it turned out OK, I'll have to redo Ultimeca's castle (and unlock the other abilities, and prepare better), so I can enjoy the ending.
There's nothing quite like finishing a great game for the first time. What was your first time finishing the game like?
