The Japanese version of the game did not feature voice acting, or an orchestrated soundtrack like the North American and European versions. This means that the English version of Dragon Quest VIII was the first time voice acting was used in the series.

Jessica's appearance changes when wearing

• Jessica's Outfit
• Dancer's Costume
• Bunny Ears, Bunny suit and Fishnet stockings
• Magic Bikini
• Dangerous Bustier
• Divine Bustier

If she is wearing a different combination of items, she will revert to her standard appearance.

There is a room hidden in the game where a bunny girl will give the character a "puff-puff". This is an implied sexual act where the character is blindfolded, and the bunny girl rubs two Slimes against the character's head as if the Slimes were her breasts.

This can be performed to all 4 characters. Amusingly, if this is done to Jessica, she will appear angry with her arms crossed, tapping one of her fingers.

The name 'Dragon Quest' was trademarked by Simulations Publications, who used the name for their Pen and Paper RPG. Because of this, the name of the series was changed to 'Dragon Warrior' in North America until the release of Dragon Quest VIII: Journey of the Cursed.
