Nope, never. I've had a few friends who have hit it by a bit, not a life-changing amount but enough to splurge for a couple of days to a week with no problem. That has never encouraged me to try to achieve it though lol, kind of ignores the purpose of having fun by playing it since you're now playing it to earn money, which is a trap zone that's pretty hard to escape from if you fall in it. Nonetheless I have felt jealousy over it, I just never let it go over my head.

As for jackpot stories, I'd have to hit one first before telling one
