Well the Masamune of Japanese legend was a blade so sharp it never drew blood, so that and the not wanting a higher rating is what they were going for.
Although as for people calling Cloud 'emo', it's a pet peeve of mine. He has all his hopes and dreams destroyed, his childhood town burnt along with everyone there, including his mother, tehn he's experimented on for years and has his mind broken, then Zack dies, then he sees Sector 7 destroyed because of him, then Aerith dies, then he finds out his entire identity is a lie that Tifa (who he probably trusts most) didn't point this out to him, remembers all the shit he went through before, gets Mako poisoning and puts everything aside long enough to save the world and then people complain whenever he's upset. Gee, I wonder why he's feeling blue?
I'm not saying Cloud is an amazing character, or that FFVII is "teh bestest gmae EVAR!!!!11!!!1! n u iz teh n00bz iff u fink diffurnt!!!1!!!!1" so please dont' mistake me for a whiny fanboy. And I'm really not trying to attack you or anyone personally, but Cloud, Tifa and Aerith's characters are accidentally or deliberately misunderstood so damn often it really bugs me.
