I tried, I really did, I tried to start over, to play through ME3 with a renegade femshep (the opposite of my original) like I intended to after I beat the series before I knew how it ended. Honestly though? I just couldn't stay attached anymore, what had originally been a new and exciting experience was spoiled completely by the ending I knew was coming. Good games are like good books for me, I go back and I read them/play them again because I want to hear the story being told one more time. It's the reason I've beaten Bioshock 9 or 10 times since I bought it back when it first came out. It's the reason I still occasionally dust off KotOR and KotOR II and play through again. Mass Effect isn't a good book anymore, it had all the makings of one but the ending just killed it. A good ending can save a mediocre book, but as ME proved, a terrible one can absolutely cripple even the best story.
