Yeah, I started with my so-called "perfect save" about 2 years ago. Last summer, I went to disc 3 and I am right now, putting finishing touches. As of right now, I have:

1.) all charas. lv. 99
2.) have all materias
3.) have 200 materias all master
4.) have all items in inventory except... let me check...21
5.) beaten ruby & emerald
6.) have a gold chocobo(working on having 6) & all chocobos in farm is in rank S
7.) clock went around once and now is 20 hours
8.) have everyone's ultimate limit breaks & weapons
9.) have 4x cut for 3 characters.
10.) have ribbons for every character
11.) mastered all 4 enemy-skill materia
12.) did my best for all wonder square games
13.) have 2 master summon, 2 master command, 2 master magic (hehe...)
14.) have all characters with limit gauge full
15.) saved right before fighting sephy
16.) my party members are: hyper
17.) things set to "fast" (atb, battle/field message) so I can beat game as fast as possible.
18.) learned aerith's ultimate limit break (doesn't really matter tho)
19.) have aerith's ultimate limit item nevertheless.
20.) have mythril

...I'm sure I missed something. Yeah, it took me a while to get to this point...VII RULES!!

Things I'm working on:
1.) morphing to max out my charas stats.
2.) having 6 gold chocobos
3.) running away from battle 9999 times to do 9999 with chocobuckle
4.) get maximum amount of GP (right now, i have over 2000)
5.) I think that's it...

Yeah, so Blathnaid, what's the point of doing some of the things you're going to do? (example: getting highest BP? I mean, what's the point after you get what you need?)

Yep, so that was my ultimate save!!
