I like the item system in Tales of Phantasia. You're only allowed to carry 15 of each item, which is still a lot, but makes more sense than lugging around 99 Potions, Hi-Potions etc.

Also I loved how you could fill a food sack with food to slowly replenish your HP as you walk.

I also wish for more armour. I miss being able to equip a sword, a shield, body armour and an accessory or two. These days, it's like equip a weapon and a...bangle/bracelet.
