Explore the world

Dragon Quest III HD-2D lets you turn on a quest objective marker on your map screen, which plainly spells out whatever destination you need to visit next. For players who don’t feel like remembering clues, or just want a relaxing adventure, this is a nice feature. That said, this was not how Dragon Quest III was originally meant to be experienced, and means you can miss entire major dungeons by following waypoints!
Additionally, Dragon Quest III HD-2D massively expands the original game’s world map to include random treasure to find, and “secret spots” which can hide collectible items or monsters for you to wrangle. You’ll often find yourself well rewarded for venturing off the beaten path.
