sorry krepe, I should have explained, RetCon= retro continuity.it means that if we said the mayor of new vegas was a dude named "The King" before we knew about Mr. House, we would have to change it as we continued through the story. so... if we said hoover dam was filled with ghouls, and in the real game, it was filled with super mutants, we would have to ignore we ever mentioned ghoules and pretend we were fighting super mutants all along.
