Why do you think the characters in FF games,have such big weapons?

Yeah of course, Cloud is the ONLY character with a big weapon. :rolleyes2
Actually, you'd be able to find loads of characters with massive weapons since FF7, and at LEAST one in the FFs before then.

Actually Yuffie's Shurikun isn't too oversized, although Squall's gunblade is ridiculous.

Some of the swords in FFVI (especially Atma Weapon) were longer than the actual sprites of the characters. Plenty of characters have had massive weapons. They're much better for hitting the weakpoint for massive damage obviously.

You're forgetting time period, in order to make a detailed weapon in FFVI they had to buff up the size of the image.

Why?
Simple, people dig huge weapons. They found that out when Sephiroth and Cloud got all of their fans and now their milking it for all its got.
