It's POSSIBLE that Ninja theory may have used SOME ideas from Divine Comedy. And it's even possible that they may have come up with ideas from looking at Dante's Inferno the game as well.I am aware that DMC is based off the Divine Comedy, but then in some way, so is DmC Dante.
I see it like this:
The Divine Comedy > Devil May Cry (the original series) > Devil May Cry (the reboot)
Both games derive from the same source. Sure, DmC is a step further, as it is a rendition of the original series, but they may still share the same source. Neither of us can be certain about any of this though, since we have yet to get proof of one or the other from the developers.
But DmC Dante is first and foremost based on DMC 1 Dante. If there can be more than one source as you suggest then DMC 1 Dante is the primary source.
I am curious, what ideas in DmC do you think is borrowed from Divine Comedy?
P.S If DmC is based off Divine Comedy directly then that would make DmC a parallel universe of Divine Comedy.
