Hey Geek,
In my opinion you would make a great deal more from the casino games as you would be paid on the losses of the player rather than a percentage of the rake. OK they may win from the room, but they will come back and lose those winnings and more, as they feel that they can still clear up no matter what the costs.
However, you could get yourself a poker player who plays big tables thus racking up more rake. It’s swings and roundabouts and both can be as profitable as each other, but I think Casino losses are greater which make your commissions….well greater! :happydanc
Hope this helps?
