Scarmiglione, Cagnazzo, Barbariccia, Rubicante, and Calcabrina from FFIV are all Divine Comedy references.

The Final Fantasy wiki has a pretty exhaustive list. Here's its page on FFVI's allusions, for example. Some of them are pretty subtle; I got the Pandora's Box reference the first time I played the game (it's worth noting that one of the enemies in the game is also named Pandora in the SNES translation), but others are a lot more subtle.
