It's not fair to compare a NES game to one which has been designed with gambling psychology at it's core - one that surpasses even the slot machines available to adults.
I guarantee you didn't need to delay gratification for 4 hours while waiting for additional coins. Nor did you have the option to spend real dollars (with zero chance of winning; now the house has 100% chance to win! you know they're loving that!) to get that gratification in an instant instead.
Would you rather your son or daughter be coked up in order to learn about the perils of drug use or is that different and something that makes sense to teach through observation?
I have no issue with these games being made to available to adults and I'd even support real money wagering but Apple need to reclassify these games as adult only and not as a "card game" which is "suitable for ages 12 and up".
