There could be a number of different factors at play here, but one could be that when it comes to games that stay with you it's the characters and story that left the most impact, while in games that are the most enjoyable to play it's the gameplay that shines the most. So you might still remember it fondly in hindsight because of how much fun the game was to play in terms of gameplay, but can't recall many specific things about the game because the story or characters didn't leave as great an impact as some other games did.
Of course, it could be something completely different too, but that's one reason I could see for it at least.
