Jump has a detailed look at Dragon Quest X: Waking of the Five Tribes’ town and you can own a piece of it. Players can build a house in Astordia in a residential block of the town. Houses can be customized, but Jump didn’t discuss this feature in detail.
Dragon Quest X’s hub world also has an inn where you can rest at to restore HP. The ground floor has a concierge too which informs players about events in the game. Screenshots also show a blacksmith, likely a place where you can improve your equipment and create new items, plus a bazaar. You can display wares at the traveler’s bazaar. Sounds like that’s going to be the place where you can sell gear to other players. Dragon Quest X also has a post office and Jump hints that you may be able to send letters to friends and perhaps even give items to other players there too.
Dragon Quest X comes out next year for Wii and will also be released on Wii U at a later date.
