Gambling includes plethora of games, various sports to bet on but doesn't it all boil down to money in the end? More the money involved, more the thrill.
Suppose, as title says — you had infinite amount of money, would you still gamble?
Personally, I can't see myself giving two fucks when I don't care for money in first place. Would you?
Whole idea of having infinite money doesn't exist in this reality, and even if it would exist, don't you think it would render the whole act of "gambling" pointless. You should call it playing then, because gambling part wouldn't exist. You wouldn't be able to lose money, and winning it would be pointless, thus you aren't "gambling" per se.
But when it comes to playing, i sometimes play demo modes in slots just to calm my brains, and there's no financial incentive. I don't call that gambling but i probably would do that sometimes. Although, it's hard to imagine how i would spend my time when i had endless resources and sky would be limit with possibilities. It's fair to say that i might find something else to do.
