I've NEVER bought this argument of sliders playing differently in Play Now v. Dynasty games. Of course games are going to have different outcomes its called variance. However, having played a ton of play now and dynasty games messing with sliders I've seen NOTHING to indicate it changes anything to any statistical significance.

The problem is people hear this then see a slightly different result and think they have stumbled on to something. Play a large enough sample size of games and the variance goes away with a few outliers here and there in both play now and dynasty games.
