Well admittedly he was powerful but the way I see it, I could hit with a sword that was doing 8000 damage in a matter of seconds. If I used a limitbreak then multiply that by 10. Real time was the problem there since I could do more damge in shorter time. I've not played any others so I don't know if it's still a problem with FF games.
Oh, you have no idea. If you can get your hand on FF7, use Knight of the Round summon + Quad materia + Mime command.
You can go away, do housework for an hour or so, come back -- and the Knight of the Round animation would still be playing, provided that the enemy isn't already dead. (Ala Ruby/Emerald/Ultimate weapon.)
