ARGH!!! I HATE SPOILERS!!!

Okay, this is now the fourth time I've had a big game spoiled on me. First, it was Killzone 2 (which wasn't too bad, because I didn't care all that much). Then, it was Uncharted 2. Then, it was Heavy Rain. 
 
Now Red Dead Redemption has been spoiled on me. 
 
I was just reading through the forums here on GiantBomb, trying to find tips for the challenges in the game (which are ridiculous, by the way), when I came across spoilers for the game's ending.  And of course it had to have a HUGE twist, rather than just ending. 
 
Stupid plot twist spoilers. I hate them.
