GI - "I suspect that Naughty Dog's The Last of Us is going to be many people's game of the year. It's certainly mine. It's an experience that has stayed with me long after I finished it. In the months that have passed since it released, I've continued to think about the game's ambivalent ending and what it means."
This is a game where your opinion of the characters determines whether or not you agree or disagree with the ending. I as a father, can understand the final outcome and personally feel I would of done the same. Be it selfish or whatever. In that scenario, it's too difficult to truly know. TLOU isn't black and white, but a shade of grey that tears at emotional strings, strumming a tune unlike anything else.
how many endings in video games are analyzed to this extent? Very few, which demonstrates the brilliance with how it ended.

The world was already gone to shit anyway, no justice system, full of rapists, murderers and cannibals. There's no going back from that, sacrificing Ellie would have just been a waste.
Don't contemplate it. It'll mess with your head and cause depression.
