Part of the reason for that, according to Platinum's Atsushi Inaba, is that Nintendo have known when to let Platinum just get on with it, but have also provided some pinpoint advice and no small flair for incredibly detailed critical feedback.
"You have a certain image of a company, and in the case of Nintendo, we've found it's been really nice to actually work with them and find out what that's like," Inaba told Gamasutra.
"They know a lot about games, and they've been really great to work with. Our relationship so far with Nintendo hasn't been very long, but so far it's been a great experience. Not to say that we won't have some serious fights over things later, but so far it's been good."
"In certain terms, there have been instances where there's been feedback Nintendo brought to the game -- where we come up with something and they'll be able to play it and provide it with feedback that we've been able to use," added director Yusuke Hashimoto.
You tend to get tunnel vision when you're working on a game, so when suddenly this volley of advice lands from the outside, honestly, it's refreshing. [...] And all of the things we want to do in the game, they're not standing in our way, in that sense. But it's almost as if they are a very critical player that can sit back and give us great advice on how we're creating the game."
According to Inaba, Nintendo's eye for detail can prove a little "unnerving".
"Working with Nintendo, one thing that comes out of that is that we're not able to cover up weaknesses in the core gameplay by making the graphics prettier or adding cutscenes, or whatever," he said. "The concern, first and foremost, is the core of the game and the quality of the gameplay. They really have our back in that sense. And that's actually a little bit unnerving, working with people who are such perfectionists in that sense."
It sounds like the two companies have managed to get the balance spot on, but we'll have to wait until next year to make a definitive judgement on that. In the meantime, though, check out our Bayonetta 2 hands-on preview.
