On the other hand, if you watch F/sn first, you know how the Fourth Grail War ends - but this isn't a bad thing. These are all major reveals in Fate and Heaven's Feel, and I think that knowing these things in advance impedes one's enjoyment of those routes. If you watch F/Z first, you know how messed up the Matou family is you know that the Grail is corrupt you know about Kiritsugu's affiliation with the Einzberns you know that Sakura and Rin are sisters you know that Kotomine is not a good guy.
On the whole, though, I feel that watching F/sn first is the correct choice, since this is the "production order" of the series - the F/sn visual novel followed by the F/Z light novels.įor incredibly spoilery details on how they spoil each other, see below: There are pros and cons to watching F/Z first vs. When Ufotable's version of Heaven's Feel comes out, watch that, too. Then, watch Ufotable's version of Unlimited Blade Works. Then, once Ufotable's version of Heaven's Feel comes out, watch that.
At some point in the future, Ufotable will release a movie or series of movies that will adapt Heaven's Feel.
