I’m going to go ahead and declare the Mass Effect trilogy done for good now that the Citadel DLC arrived and finally gave (almost) everyone the ending they wanted for the series. But it’s a big universe, and just because Shepard’s arc is over, that doesn’t mean the universe will dissipate. Rather, it’s likely only just getting started.
Going backwards is cheating. It’s the easy way out when you don’t want to innovate and move your story forward in any meaningful way. You already have the ending written, and have probably established some of the pieces along the way. Making a prequel, you simply have to fill in the blanks, and people fail to realize that sometimes it’s a lot more interesting to leave blanks blank. Just ask Boba Fett.
I like some of these ideas. I think Mass Effect 4 starring Liara or Garrus (or both!) would be a pretty cool idea, though honestly I’d love an entirely new series where you once again got to create your own character. Maybe you could even choose your alien race this time?
Perhaps such a game will exist at some point, but until it does, I do imagine we’ll see at least a handful of Mass Effect spin-off prequel titles like the ones mentioned. Maybe I’m wrong. Maybe they could be great, but I think like so many other series Mass Effect would be better moving forward than looking backward.
