Personally if I'm going to play a lottery, I'd rather one with a smaller top prize and more prizes/higher chances of winning something.
Here in the UK, our own National Lottery has an average jackpot of about £5m (~$8m) and rarely goes above £10m (~$15m). You have to match all 6 of your numbers for the jackpot and there are 49 balls being drawn from.
We do have a Europe-wide lottery called Euromillions which sometimes gets quite large, although there is a cap around €150m (~$200m) which after the jackpot reaches that level, additional prize funds are spread down to other prizes and the jackpot remains static.
I don't honestly feel that winning £500m would change my life significantly more than winning £100m, although obviously I know which I'd prefer. I just think once I reach an amount of money whereby I'm never going to have to work or worry about money again (unless I screw up massively somehow!), additional winnings on top of that are unlikely to add much real value to me, so I'd rather play a game with shorter odds and a reduced top prize.
Or do what I usually do and forget to buy tickets at all.
