No, you never ever EVER use apostrophes to make a plural! Grammar atrocity of the worst kind!!!!11

Since 'Final Fantasy' is a product name, and not just normal use of the word 'fantasy', it's OK to pluralise it as 'Fantasys'.

If you're talking about the Toyota Camry, and you want to mention a lot of them, they'd be Camrys, not Camries.
