Demon's Souls and Dark Souls director Hidetaka Miyazaki is upset about leaving the series, he tells Edge. Dark Souls 2 has been passed to a new pair of directors, Tomohiro Shibuya and Yui Tanimura, a move that was "a company decision" according to Namco Bandai producer Takeshi Miyazoe, and was essentially done to inject the series with some fresh blood (large stains of it, no doubt).
Despite his feelings for the Souls series, Miyazaki admits, "Sometimes I'd like to work on a warmer game – not necessarily casual, but warmer in terms of the atmosphere and the environment." Given how pervasively gloomy the series is, we can understand how being mired in it every day might be draining. Furthermore, while Miyazaki is "sad about not being involved" with Dark Souls 2, he says, "Maybe this is the time to have new inspiration, so I'm fine about that."
For his part, he says that he is eager to play Dark Souls 2 "with a little bit of distance." The development team, fans and the press all understand "what the core of Dark Souls is," he says, and that core "will never change." Finally, while he'd rather not see "Dark Souls 8," he adds that the important thing is serving the series' fans. "We want to stay true to what they expect."
