Personally, I don't like to see the games get harder just for the excitement of a bigger jackpot. It just doesn't excite me like it does most people I guess. I ain't gonna live forever, I'd rather experience the excitement of winning a jackpot, any size jackpot, sometime before I breathe my last..
Hell, I play Virginia's Win For Life game with odds of 1 in 5,245,786 and it seems like NOBODY ever wins the Jackpot EVER! And it seems like very, very rarely does anybody even win the 2nd place prize of $52,000 with odds of 1 in 874,298.
They pay out a few $600 third place prizes a week and that's about it. And the odds on this game are "easy" compared to MM.
MM's odds are already in the "almost impossible" range and now they're going into the "might as well forget about it" range for me.
