So dissatisfied are players with the trilogy's conclusion that a fan-organised campaign, dubbed Retake Mass Effect 3, has garnered support from thousands of users on Facebook, Twitter and the BioWare forums. The movement has even raised over $50,000 for gaming charity Child's Play.
In a post on the studio's official forums, community coordinator Chris Priestly writes: "We appreciate everyone's feedback about Mass Effect 3 and want you to know that we are listening. Active discussions about the ending are more than welcome here, and the team will be reviewing it for feedback and responding when we can.
"Please note, we want to give people time to experience the game, so while we can't get into specifics right now, we will be able to address some of your questions once more people have had time to complete the game.
"We understand there is a lot of debate on the Mass Effect 3 ending and we will be more than happy to engage in healthy discussions once more people get to experience the game. We are listening to all of your feedback."
In the meantime, Priestly requests that users limit plot discussion to the relevant area of BioWare's forums, and keep its social media channels free from spoilers.
