If compared to, I'd say this is literally Avengers Endgame but better. Because it made me feel something different from when I watched that movie. Sure I wasn't reading comic books from a childhood, the best I had was following through, watching all the MCU movies. But nothing hits harder than this.
The beauty of FGO is that you spend time and bond with every character. While saving humanity, you come to know every one of your allies personally. Seeing them all stand in this last stage was enough to tear me up... and even when knowing how the whole story goes... basically a retelling of the same amazing story, I still teared up all the time.
How can I not? this movie was the culmination, the climax of all the time I've spent in the game. It was the end of one long journey, full of meetings and partings. Remembering all of that makes my heart heavy.
Really, I can only thank you to TYPE-MOON and Cloverworks for making this amazing movie. To see this part get adapted into an anime, not only that, but done very well, staying true to the original story, dialogue, soundtrack. I'm sure it's the best gift for any FGO Player. I can really take my breath, clear my heart and mind, and say "it was worth it. it was a fun journey."
