1- Mobile is a vastly different experience to traditional gaming only reason to even bring it up when replying to what I posted is if you're implying it's competing heavily otherwise it's an irrelevant thing to bring up unless you were trying to say mobile can support traditional developers which isn't true as it doesn't generate anything near enough to keep them a float. The low budget part was a misread as I thought you're implying that 3DS is there for the lower budget games and not mobile.
2- The smaller gap is significant because Switch has access to modern features, arhitecture and tools to help deal with some of the issues that can arise this is what you're ignoring. 3DS, Wii and Wii U not only had a bigger gap but non of the mentioned, again not sayinf VIIR is definitely coming but it's more plausible than the support for prior platforms.
3- What I mean by XIII is that many FF fans had this grand vision of what it was going to be like and thought it was safe to assume so instead the game was heavily linear with only one real large open area that you had to play through 2 thirds of the game through to access, the are no safe assumptions with modern SE.
I'll call it episodic until they show me an execution that highlights otherwise because again explain how it's going to be executed, the full game to me is if we're able to go to Sephiroth in the Crater which is indicated won't happen. The remake will be segments of the original game redone and extended into several games until the final battle from what is indicated which is an episodic approach no matter how you word it unless they show us an out of the box BOTW approach I can't class it in any other way.
To give an example if Nintendo said they're remaking OOT and said it will be over several games how else would you class it especially know how the game plays out?
