So finally got a "Game Over" Tidus was confused, rikku dead and lulu tossing a Pheonix Down, luckily I only lost like 10~ minutes.
I always try to save even if it's just after doing a few fights.
I always try to change every character in to get AP points and try Rikku to mug or steal items. If most characters can get a slotted item with auto phoenix it helps on some fights because it doesn't waste a move.
I don't know why, maybe because I played FFX on different versions like the JP and International version, but Auron seems to be missing somethings. I always had him with First attack and 1 MP, but he has neither this time around...
Maybe because I am using the US grid maybe..
