I don't think a high enough dollar value is enough to make it worth playing. Over a certain amount, the winnings are simply just "arbitrarily large". If the prize was a trillion dollars, but each ticket cost $100 to play, does that mean it's now worth it for everyone to buy a ticket? You're still not going to win. I think stuff like this should be weighted towards chance of winning. Given the choice between a 1 in a million chance of winning $2 million, or a 50% chance of winning $4, I'd pick the $4 one every time. They have the same expected value, but one of them gives me a chance of winning anything at all.
