Mushroom Men: The Spore Wars, offers his thoughts on the market for "core" Wii games, his own game's chances on a system dominated by Wii Fit and such, and designing a game to be accessible to a wide and varied audience.
Oh, and he calls out Deadly Creatures. When asked if he's familiar with Rainbow Studios' critter-based brawler, Borth responded with: "I have heard about Deadly Creatures. I have many opinions on that game, especially how it came into being right after THQ received our pitch document for Mushroom Men. I will let you draw your own conclusions."
We can't say if there really was any such malevolent behavior behind the conception of Deadly Creatures, but oh snap just the same. And while we may not have seen a parallel before, now that he mentions it, they're both 3D action/fighting games about small creatures adventuring, unseen, in the human world. But we still think Creatures could turn out awesome.
