It's an IC issue. Everyone can literally buy pokerstars chipset online or some random poker set in a local store. The real poker games among the criminal roleplayers happened quite often, it was a mix of almost every mob sending their men to play in set places. As far as civilians wanted to play, they did their own thing, the factions ran their own joints. I see the point, making the games ran by facs so the average joe could get in debt and all, but having script restrictions is a bad way to go.
