How do you get your world to leave Age of Myth?

[Gonzo]

Im messing around with world gen at the moment and mostly coming out with age of myth, first i tried large land, 500 years line, high civ count, medium sites, low beasts, high natural savagery.
2nd time i tried a similar gen, except with very low beasts and medium natural savagery, what could it be that is preventing my worlds from passing age of myth? it picks up real early on and then stays the whole distance of 500 years. could it be the large land mass size?

add more population and less monsters the timer for it to look for is set to 100 years to prohibit rapid switching etween ages

Age of Myth is best age though.
Lots of monsters and rising civs.
