While it might seem disheartening that a game on a new platform is apparently so similar to its cross-platform counterparts, Mr Hutchinson sees it as a good thing.
"It is exactly the same game that's on the other platforms. And I know that sounds ridiculous, but it's been a long time since I've shipped a game on more than three platforms where you could say it's all the same. It's not like some radically diminished version, so that's exciting."
