Your calculations sound great. That was pretty much what I was figuring, that Sephiroth was early 30s in-game. Here's a nicely speculative question, then...what did he DO in the 5 years between going nuts and killing Pres. Shinra? Hmmmm.... I don't know either....

Re: Vincent. Yeah, he's from a different generation than everyone else, but then again this is the FF7 world. Who knows what their sixty years ago was like.... ;)

Thanks for the info! ^__^
