I know in the other thread, I mentioned how it would be nice but their time is better spent on moving forward rather than revisiting the past of the series. I wanted to expand on this a bit.
Now, if a remake for Days was in consideration, they have to decide over a few things:
1) Old style or new style? Whenever people discuss a Days remake across the internet, this creates a lot of split views.
On one hand, they could totally use the old style and development probably won't take forever. They would have nearly all of the cutscenes animated and voiced. Most of their time could be spent on developing the gameplay system and deciding how to implement MP. It would be cheap and quick beyond the MP elements which would probably be the more costly aspect if they decide to do it.
On the other, now that we are in a post-old style age, why should they keep reusing the old graphics? This is their opportunity to create something beautiful. They can reuse some KH3 assets and create new ones that can be used in future games depending on what properties they wish to revisit. The thing is, it would be costly and take up a lot of time to develop.
2) Is it worth spending money on a Days remake? Regardless of which option was chosen, is it worth spending all of that money to make this happen?
3) What value is there in revisiting Days? What sort of importance does it hold for the future of the series?
