Be the king of your own Dragon Quest X: Waking of the Five Tribes castle, even shortcake castle. You can create a home in the online RPG, but first you have to purchase land from one of the residential plots. Then you can place a home by using a "home kit" item. Square Enix has different options like a tent (for gold strapped homeowners) to slime houses.
After your home is decorated with virtual items you can invite friends over or use your home as a place to craft equipment.
Thieves might want to use their home for loot storage. This Dragon Quest X class has a treasure hunting skill they can use on the field and Hypnos hunt which deals extra damage to sleeping enemies.
