My problem with Amnesia is that it kind of just becomes central to the character, which isn't great. It's okay, but when you ever RP with a person using the amnesia thing, most of the time it just comes up so often, you know? It's kind of like... in your face all the time "I can't do this because of amnesia. I don't know that because of amnesia. I can't remember that thing because of amnesia." It's often almost tiring to RP with those types of people. It just sort of becomes that character's one single defining characteristic.
That's not to say that I don't think it can be done well, but I've yet to experience a truly compelling amnesia story. I think that if you really want a character that doesn't really know much about Eorzea because OOCly, you're not familiar with the lore. I think you should just go ahead and do that. Have them grow up in a secluded village and venturing out into the wider world for the first time. Most of the time amnesia is tried it just feels lazy to me.
