Of course not FF VII, but I'm not sure about VIII.

FF VII is one of the biggest selling games ever made.

However many fans of the game admit its because they though Sephiroth looks awesome.

Not saying all fans think that, but there are a huge number that do. Same thing with liking Squalls Gun Blade.

You never hear a fan saying they liked FF IX because Zidane's Daggers were cool.


Point being, FF VII has those kind of sales because a lot of people are superficial. And again, not all the fans are like this, but there are a good number of them.
