(Spoilers ahead). Let me start off by saying I only finished Mass Effect 3 last night, having read no reviews or anything before or during gameplay. Afterward, I posted about it on Facebook, and in the comments became aware of the so-called "universal outrage" over the way the game ended. After some quick reading about Why Mass Effect 3's Ending Was So Terrible, I became enraged about the outrage. This all culminated in the following ejaculation: GROW UP, GAMERS. Every friggin' game can't end with the Ewok cuddle patrol dancing and chanting "You sure are special, kid!".
Just to sum up for folks who aren't interested in experiencing the "moment" for themselves, the main character (Shepherd) ends the game with a very tough decision.
