I never played the original. So I can’t really say how much will be lost in this remake. As being developed for consoles will obviously remove any adult content of the original. Though being a Type-Moon VN is rather likely that said adult content was pretty unimportant in the original as well.
So it’s probably not going to end up being another YU-NO. However would be nice if together with the remake they also made the original easier to get.
