Should Graal have games of luck and chance?

[konidias]

I was thinking about making a small casino of some sort, that would have some chance/luck/skill games in it, where you could win prizes and money. The only problem that struck me was that would people like this idea, or hate it? I remember everyone wanting a Graal lottery (I could include it in the casino) But is it really the best thing to have? I mean what if someone gets lucky and wins a lot? What if you don't get lucky and lose money? Will you be angry, will it throw the economy on the server WAY off?

Some of the games I planned on having are:

BlackJack
High/Low Game
Lottery
Slot Machine
Spin the Wheel
Roulette
Prize Grab Bag

So I just wanna know if the majority agrees on something like this, before I go making it all and finding out people would be angry.
