Pokémon GO proved to be a massive success back when it launched in 2016, so it’s natural that other franchises want to make their own AR inspired games.
Unlike Pokémon GO though, Dragon Quest Walk appears to be more rooted in the JRPG formula of its core series, as the teaser showed a battle more similar to the ones in the mainline series.
Dragon Quest Walk has been announced for iOS and Android mobiles, with a 2019 release schedule in Japan. No plans for a localization have been announced for now.
