I just finished the game. I got the good ending and i absolutely loved the game. I still am going to explore this wonderful world more.
But first i had to see the other endings on youtube. So I saw the bad ending and the "other" ending.
The"other" ending FLOORED me... I dont think that this thing has ever been done before in a game. It is outstanding and in fact it makes you feel like you got a great mindfuck. It is not cheap, it is not bullshit, it is clever and by God it makes you see the entire game in a whole different perspective. Kudos to the guy who had the idea, and the balls to implement it, huge respect!
