I don't know what to think... A lot of what the last of us was about had to do with redemption for victims of life on life's terms. I have NO desire to play a character like what Abby seems to be, but I do think there's room for playing a character who does what the leaks says he/she does and learning from it if it's handled well, which we won't be able to tell without the context of the whole thing.
On top of that, troy Baker recently talked about Druckman directing the first one. He said the whole scene where Joel's daughter is playable was meant to just be a quick cutscenes but Druckman wanted her to be playable and to see what's going on from her perspective in order to bring more life to the character so that you empathized with Joel. I mean, that whole first section of the game is like maybe 20 minutes but it's some of the best story telling around.
So I don't know... I think Abby's story COULD be interesting... We ALL knew that Joel killing that Dr at the end was him selfishly damning the world, and there's fallout from that. When I played it, I was under no illusion that it was the good choice.
But again,based on the leaks... Joel and Ellie deserve better.
