For me, it depends how much of the game is story-driven, how long a campaign takes, and how dynamic the gameplay is. I've never replayed an assassin's creed game (from 3 thru Odyssey), but rank them highly. I consider racing/sim games "replayable" in the sense that I never finish the absurd number of championships but will binge them for a while as I buy more dream cars. Similar story for battle Royale/arena/non-story games like rocket league or fortnite. My most-replayed game series is Ace Combat (4-7), but that's because the campaign is only about 5 hours typically and offers more variation in gameplay along with attainable medals. Puzzle games like Portal 1/2 or The Turing Test offer replayability to me because I never really remember all the tricks to the puzzles, but that's like 5 years between replays to not spoil the entire story.

This is also driven by having less time available to game. I wish I could learn 2 games every week but a good gaming week has 10 hours of gameplay for me. It's usually less than 5. So there's a little more motivation to play something familiar so I can start having fun faster. Ironically, Elite: Dangerous is a comfort game despite the common complaint of its complexity. Some PS2 era games come to mind
