Not sure how many people have asked this but I'm confused about it. I know that it's better for a player to have a lower volatility, but what exactly IS volatility, and what does it affect.
It affects the ratings that the player has in blue. Non physical attributes. Low vol means that the swing in either boom or bust is not very much and can take awhile. Hi vol you have a greater chance for a much larger boom or bust quicker. Having said all that, vol is not a guarantee either way just a higher probability. There are several threads and blog about it for your reading pleasure.
