FO4's ending is even worse than FO3's ending. At least FO3's ending reacted a bit to what you did (showing images of certain quests and actually having at least 3 versions of the narration) FO4's ending is exactly the same for everything, it's short and the only variation it has is a single sentence added for helping the Institute. Not to mention the playable part itself of the end game is jank and clumsy, with the Institute and Railroad basically being the same questline until the end, with the Institute ending just being an aticlimatic shooting of a bunch of NPCs in a small cell and the game just farting the ending.
