The biggest difference with Vegas is the direct relationship between time and energy spent gaming and money spent. The Skinner Box phenomenon is directly harnessed to empty peoples' wallets in a way that you don't see as completely with other forms of addictive games and entertainment.

But I do feel that things like scientifically designed gambling are certainly on the dark side of the divide.
