You do realise that DmC is NT's product? Because somehow I have feeling that you missed point that game written and designed by NT. Porting existing asset has nothing to do with creating it.
Okay, let's back up a bit here: When you say something is someone's product, that means it's owned by that person. In this case, you're saying DmC: Devil May Cry is Ninja Theory's
product. No, it's not. They only developed the game. And as for
bolded:
No, I didn't miss that part.
So basically Capcom legally owns DmC and they can do whatever they want with it regardless of NT's input. So while they can make a DmC2 without NT, the question becomes should they? That is a tricky question because its more about how you see the creative process and artistic integrity etc than a business perspective.
Yes. Creative process and business has nothing to do with each other. Each video game itself is a business selling you a
product. Ninja Theory was the creative mind behind the tone and direction of the game. But it's
still Capcom's product. They
can follow the "template" set by NT.
Should they? In your opinion, it's "no." But Capcom can do it anyway. It's not up to you whether DmC: Devil May Cry 2 goes in this direction or not. If you liked the first one, your wallet tells them "I like this." And if Capcom goes to NT and asks them to make a new entry, there's no stopping them from making the game multiplatform. They own the trademark rights to the series itself. Nothing stops them from asking NT to do it. Nothing. Not even being owned by Microsoft. The only thing Microsoft owns is the team, assets, and IP's that they own. DmC isn't part of that deal, because the IP is a CAPCOM property. Nothing more and nothing less. If Microsoft wants DmC: Devil May Cry 2 to be exclusive to Xbox like they did with Dead Rising, then Microsoft would have to throw money at Capcom to make it happen. So, it goes back to my original assertion: Nothing stops Capcom from making a sequel.
Besides, Microsoft and Capcom has been partners for years, so this will go smoothly than you expect. On top of that, Microsoft has allowed multiplatform development. Minecraft is allowed to be on every single platform imaginable regardless of Mojang being acquired now.
Oh, and one more thing: DmC: Devil May Cry was developed using Unreal Engine, so it's not really that hard to modify the engine that NT made when they developed DmC: Devil May Cry.
I'm open to a new dev team but I rather NT continue because it is their project and born out of their creative impulses that we wouldn't get through a different dev team.
However, as I said before, nothing stops Capcom from doing what you're saying. Nothing.
It's practically what Microsoft is currently doing with Gears of War.
