Somehow, this isn't that surprising. The survival/crafting genre has exploded into public consciousness since Minecraft quickly became the most popular game on Earth. Knock-offs, clones, and would-be successors to that throne have been mostly quarantined to low-priced Steam releases thus far. It was only a matter of time before major, established brands began swerving into that territory, too.
Even so, it seems like a particularly odd fit for Dragon Quest, a series that has rarely strayed from tradition. Even last year's Dragon Quest Heroes–itself a major diversion from the classic turn-based grind, simplistic story, and self-contained world–was simply another followed the custom of another Musou game based on a popular Japanese franchise.
Dragon Quest Builders is different, in that it's actually a very traditional Dragon Quest game in most of the ways that count: an evil overlord has taken out most of the world, and the world needs a hero to take him out.
