Personally I like the idea of games unique to cf, however simple or complex they are.

I also think that the "big spenders" who gamble a lot should be allowed access to a back room, that only other big spenders can get into. That way the major gamblers don't have to worry about gangs of thieves etc, which, if you think about it, would suit a gambling establishment. That's why if you win big enough they'll provide you with an escort back home/to your hotel.
