IMO, I would rate them: ME1 Andromeda ME2 ME3

The original Mass Effect was great, a classic, but 2 and 3 had less and less of what I’d loved about the first game. By the time I got to 3, I was playing because I felt invested in the story and characters, not because I found the gameplay enjoyable. Andromeda wasn’t quite as enjoyable as ME1 to me, mostly because I didn’t connect with the characters as much, but the story was surprising and original, fights were exciting, and the gameplay had a lot of interesting new elements that made the scenario feel immersive. It’s really too bad that so many people didn’t like it.
