I don't think Paylor would have let the 76th Hunger Games happen. I mean you're all talking about what Katniss says to prove this but did you ever think about the new president and whether or not she would agree to it? Even if she had to she would've had to build another arena and all the game makers that knew what to do are probably dead. Also, Katniss probably wouldn't have had kids of there had been a Hunger Games with 'kids' in. It would have scared her too much watching them die (she would think it was her fault), no matter that they were Capitol children. To her no child should be killed. So she wouldn't have had children, because she would be scared or maybe anytime she looked at them, she would think 'maybe I'll kill you too' or 'I killed people like you. It's my fault they're dead.' I'm not saying it is her fault but that's what she would think.
I know this doesn't prove anything but if you just read and think for a moment it shows that there was no reason to have a 76th Hunger Games.
