Ok, I've decided to test this
Kinda bored, so it gives me something to do between modelling stuff.
I've given all characters their ultimate weapons (and the next one down for certain characters like Tifa, since Premium Heart is pants unless you keep her on full limit).
Each character has 1 Master Magic, 3 Counterattack, 1 Double Cut (giving 4xCut) 2 HP+ and 2MP+ materias, all mastered. Additionally, each of them has a wizard bracelet and Ribbon.
Limit Breaks are all at either level 3 apart from Tifa who is on level 4.
At the current time, I am just running across the railway bridge towards Corel, before heading to Gold Saucer for the first time. That's taken a little over 3 hours already, running away from almost every random battle and not stopping for any items or being sidetracked by anything.
So, bearing in mind I can easily take out any monster or boss within 10 seconds of the battle starting... and having 9 hours remaining to complete the rest of disk 1, all of disk 2 and disk 3 (north crater), before finally getting to sephiroth... who else thinks this isn't going to happen in under 12 hours? And this is allowing for cheats of course, playing properly would be even less likely.
Well, back to the game
