Blasphemy! It's "Square Enix" without hyphen "-".
When I started my career at SQEX, that was the very first thing they wanted us to always get right.
It wasn't always "Square Enix," though. Used to just be "Square," until merging with Enix about a decade ago. I've got quite a few vintage (1980s-1990s) FF collectibles that all have the solo "Square" trademark. Those were the heady days of Japanese game development.
