I spent 110 hours trying to max out the sphere grid and got everyone like 3/4's of the way around it. Then I decided to fight Sin and capture some of the monsters in him to finish the monster arena quest. I did that and got about 15-20 S.Lvls. per person. So I was happy about that.
What I didnt know is that, whenever you go up the steps, it goes from Jecht to Dark Aeons to Yu Yevon. Do you automatically have auto-life here? Or does it stay on between battles?
Anyways, I found the bosses incredibly easy and it only took me about an hour to get thru from the save sphere to the end. I was kinda mad about that because I didnt get a chance to get everyones weapons and max the grid out.
I turned the game off after the credits and checked to see where I last saved at. Turns out, it was at the bottom of the steps, right before I had to fight Seymour for the millionth time. From there, can I get back on the airship and do whatever else I wanted to do before ending the game? I hope I can cuz I like to get everything possible to get the full benefits of the game.
