I'm a perfectionist. I must have every item, every weapon, every armour, every accessory, every peice of materia/magic/summon, otherwise I feel disappointed that I wasn't able to complete the game. I know it may sound strange to some of you, but I feel that these things were put in the game for a reason, and that is so you can obtain them. I hate the feeling of knowing there is something I can get, but leaving it behind. To me, it makes no sense. What is the point of there being an item that you just leave behind? So far I've managed this with FF7, 8 and 9, and I am presently attempting to do the same with 10. And after that, I'll do it all over again, but faster!
