Tales of Fantasy has a system built around the idea of saving equipment on your character. It's called the Fusion system and works in a fairly straightforward manner that almost sounds like a combination of crafting and character advancement.
Basically, if you've got a piece of equipment it can be fused onto your character, permanently adding its stats to your character and opening up that equip slot for a new equipment item. It's a simple idea, but one that effectively doubles the amount of gear you can wear. Higher level fusions require more Soul Containers, which are the sole item used for a fusion and can be acquired through story quests or instances. We're curious to hear what other design ideas are floating around in Tales of Fantasy, because if they're all this interesting it's going to be a game we spend some time with.
