Please… tell me this is a clever satire….

Seriously.

If not, this “gentleman” has some deeply-seated issues. It’s a game, it’s a story, and most importantly, it’s Bioware’s story. To the people who wanted multiple endings, there’s a logistical issue with that, Bioware has said from Mass Effect 1, that this trilogy is just a part of a greater story. So having a separate ending for every braying ass, would make it damn near impossible to do the next trilogy. So all of your choices (which are still influential in the core of Mass Effect 3), did/do matter, but the ending had to be scripted to continue the franchise.
