Suckonomics
If all the players who understand the difference between good rules and bad have already gone to PA, AC can screw with the rules with impunity. Nothing left to lose.
Some people said the PA rules will force AC to compete and I take the contrarian view, that PA will cream off the few knowledgeable players and leave the complete suckers (and us!) for AC, and neither suckers nor AP's are categories they are worried about offending with bad rules.
They could probably offer a 6:5 8D game with close to a 2% HE and the table would still be full, if they sold it hard enough. But they wouldn't make any more money! The modern ploppy comes to a casino with a small budget he fully intends to lose, he loses it all and leaves. What difference does it make if he loses it at a good BJ game, a bad BJ game, or a carnival game?
Here's the difference: there are a bunch of casinos in town, the suckers swim between them and each casino wants to be the one where he loses his $200, not the casino next door. So if you are offering a good game and your neighbor is offering a bad game, and the sucker doesn't know the difference, the money is going to end up in the other store. This is why I believe one-casino towns have slightly better games than competitive markets; they're not competing for the customer's patronage, they're competing to be the one to clean out the customer first. If you're the only casino, he's going to lose it all at your place anyway so there's no disadvantage to luring people in with good rules. That it defies normal economic theory is why gaming is more accurately termed a vice, than an industry.
