Final Fantasy X Tips

weapons and gil
this is really easy to do,
simply equip a character, preferably strong and versatile, tidus or wakka, with a weapon with the gillionaire ability and another with the master theif ability, go to zanarkand when you have the airship,
two hours later you're a mill up =].

all it takes is for you not to die and not to get bored.

once you have the gill you can start bribing for rare items like dark matter and pendulums

happy hunting =]
