If you haven't played the game you likely will not enjoy this. I didn't. Even after having played the game it's still pretty empty.
Darling in the FranXX
A beautiful, emotional ride that will keep you gripped and on the edge of your seat.
Fate/Stay Night: Heaven’s Feel I. Presage Flower
A great start to the best arc of the Fate/Stay Night series. A masterful feat of animation.
Fate/Stay Night [Unlimited Blade Works]
Different vibe from Fate/Zero, but still good and critical to the entire Fate Franchise. A little less ensemble, a little more shonen.
Fate/Zero
A gripping, gritty modern fantasy with fascinating psychological and historical elements.
Cowboy Bebop: The Movie (Knockin’ on Heaven’s Door)
A great capstone to the series (that chronologically takes place before the series ends). Definitely worth finding and watching.
Cowboy Bebop
An amazing Space Western that also acts as a great gateway to anime in general.
Girls und Panzer
A feel-good sports anime starring cute girls in tanks. It feels like a war tactics game, like Valkyria Chronicles or somesuch. I enjoyed this more than I anticipated.
Angel Beats
Feels very "Anime Kid in High School." Has a lot of great moments, has a lot of cringey moments. I did cry at the end.
NOIR
Definitely a product of early 2000s anime. Tries to be deep, dark, philosophical, and does a decent job. Action gets bland, but if you feel like taking on a slow burn mystery that doesn't require too much attention, it's decent. Music is stellar.
