This is probably the only thing that ever really bothered me regarding SBFP in general. I LOVED that playthrough and their reactions in it, but learning that they essentially faked everything and kinda pretended like their reactions were genuine really rubbed me the wrong way. I used to always go back to watch their Revengeance finale video, but after finding out, I can't really say I ever wanna go back to that playthrough again. I just really hope that was a one time thing and they don't do that kind of stuff often, since they come off as really genuine guys.
I still really don't understand why they did it (or how they can so casually bring it up). They could have just said they beat the game and honestly given their thoughts on stuff instead of faking reactions.
