Also, the reason I'm against banning such games is because when you look at all the things we find fun, you will be sad to see that a lot of them just boil down to variable reward. That variable reward aspect is what makes it fun.
You would be wrong. Even chess has variance, the better player does not always win.
Then there are games that actually integrate chance as a mechanic and are still competitive.
If you have no skill or training in chess, there's basically zero chance of you winning.
technically yes. But not all gambling is illegal. because the legal definition of gambling is more precise.
I think that's the part that is forgotten in the discussions because we conflate the casual definition with the legal one.
