That's unfortunate, I actually watched studio deen's adaptation as my first intro into the fate series, but then didn't really continue with the sequels.
I don't actually have any problems with reading a VN, in fact, I am currently reading both Umineko and Katawa Shoujo VNs on my phone. If the fate series's VN is not available on android, then well, it will take some time for me to finish it, as I mostly use my phone rather than my laptop.
I'll consider the VN and/or the anime watch order you gave, thank you for the detailed response!
I bet there is such a distro being kept hidden from us. I wouldn't be surprised. Even if it isn't public, someone probably tried doing it for his own personal sake.
