I actually came close to beating FFX without the sphere grid. It took a lot of luck and neglecting cause I didnt understand the grid at one pointOriginally Posted by Darkstalker
Beat Lunar 2: Eternal Blue with characters that have a level 33 average (well, I think it was 33, my last party member brought the average up). Oh God, that final battle was hell.
Beat Final Fantasy X, No Sphere Grid, No Summon, No Overdrive Challenge.
Beat Final Fantasy VIII a lot of times using various challenges. Solo Character, Speed Run, Elemental Magic Only, etc.
I've done more, but those come to my mind offhand. Especially the Lunar one.
