Parents have little to worry about. Some scenes might scare very small children, but kids over age 10 should be fine.
Fans of Dragon Warrior/Quest will appreciate how well the game has made the transition into 3D while keeping with its distinct art style.
Fans of RPGs should be warned that compared to most modern RPGs, the pacing in Dragon Quest VIII is leisurely, progress is relatively slow and gradual, and the storytelling is sprinkled sparingly between long stretches of exploration and leveling up. This is not the sort of game that lends itself to playing sessions of shorter than a couple of hours, and all in all it takes around 100 hours to fully complete.
Deaf and Hard of Hearing gamers should have no trouble since all the dialogue is subtitled, and there are no important audio cues with the exception of a part near the end in which the player can use a sound-producing sensor to locate some items. However, the locations of these items can be easily inferred without using the sensor.
