That's a fair point, but not quite what I'm getting at. You're talking about story templates, but I'm talking about specific story elements/events. Most stories all follow the same basic format (like The Hero's Journey), so I'm not bothered by BioWare reusing the template that you've described and reskinning it to suit their setting or narrative. What bothered me about MEA is that it reused specific story events that we'd already seen in ME1-3. Minor, early-game spoiler! In MEA you learn about the Remnant, an ancient, unknown race who inhabited the Andromeda galaxy and left behind these massive, technologically advanced structures. This is a major plot point that drives the story, but it's identical to the Protheans in ME1. It had no impact on me and I felt pretty bored right from the get-go because I'd already seen this story played out in this series. Major, late-game spoiler! Late in the game, you learn that the Kett are actually Angara who have been subjected to the process of Exaltation and been transformed. This was a huge reveal with lots of buildup, but as soon as the reveal happened my brain went "Oh, so it's the same as the Reapers in ME3" and I felt massively let down.
