「エヌマ・エリシュ!!」

Fgo is based of a mobile game. The anime skipped a lot of the main story. This is because the players voted to see which chapters of the story should get anime adaptions. The order for FGO animations is First Order Movie Camelot Movies Babylonia Anime Series Solomon Movie Moonlight Lostroom OVA If you want the full story of FGO highly recommend playing the Mobile Game.

Also recommend watching Case Files of Lord El Mellio II Fate Extra Kara No Kyokai

Also Fate Strange Fake anime

今更ですが返信させていただきます おおかたはFGOの公式チャンネルのCM、各種アニメ（Fate/stay night、Fate/Apocrypha、ロードエルメロイII世の事件簿、FateGrandOrder絶対魔獣戦線バビロニアなど）で視聴できます

そうですけど？？
