This whole "magical crystals" idea is a bad idea and has been reused by SE too often. Luckily the Crystals aren't a major part of FFIV's story, since they're soon virtually forgotten about after the first 1/4 of the game.
And it starts being uncool when it's repeated.
Same bad attitude and personality, too.but saying it's almost the same as FFIV Cid is pretty inaccurate, hell the only thing they have in common is being a builder of ships and being loud.
Yeah, it's just too bad that this similarity is not enough to make a major impact on anything in the game.EDIT: Oh and another similarity would be joining the party, but if you consider that similarity then we're just spinning our wheels already xD
