Well, I've gone and done it. I've finished Mass Effect 3, despite my, and society's, misgivings.
And it was the right call. I finished it, and the conclusion wasn't so bad, so long as you weren't wanting to analyze its feasibility. Since I wasn't wanting that, it felt just fine. I know that what I saw was not at all what the vast majority of players experienced a year ago. I had all the context of the DLC, plus the comedown of good feelings from the The Citadel DLC stuff. This helped immensely.
But I even fucked up the ending sequences, and still managed to feel good at the end. I was streaming, and someone suggested that there was a hidden fourth ending that I could choose. So naturally I shot the sky-child in the face, heard the demonic "SO BE IT...", and got the 'fuck-you' ending from Bioware, apparently the one ending added after the fact.
I didn't reset in time, and had to redo the Citadel sequence, but this time, I fucked up the Illusive Man conversation, and got laid out by the guy because I didn't want to go renegade (paragons white knighting this sucka, sucka).
But finally, I got to the choices again, and made the choice that it felt like my Shepard would make, the green choice. And it was fine. Synths and organics cum ba ya'd. The stargazer spoke to his child. And since I didn't put one thought into the feasibility of things working out the way they did, i got my mindless satisfaction from seeing Joker outrun the Mass Effect.
And ultimately, that's what this whole project of mine, finishing these games, is all about. Mindless investigation into my mindless investments. Mindless dividends are about the best I expect.
I may have also become incredibly bitter and cynical about what these games can be. But as long as I'm mindless about it, it doesn't sting so very bad.
