~ If we are honest with ourselves it is obvious that at the back of our minds there is always the possibility of making some money when we are gambling, after all if that was not true then a person will be happy playing gambling games without using any money as there are many websites that allow you to play for free or play one of the many video games that allow you to simulate casino games without the need to spend a single cent, however I think those that say that are playing for fun what they are really saying is that they do not really care if they win or lose, they will gamble anyway, and if they win then that this just a nice bonus but it is not their main reason to gamble.
Nicely put. Indeed, if there is no real money involved, it's not much of a fun, so if we want to have fun we have to bet some real money, maybe a very small amount, just a fraction of a cent, but still real money so that in a case of incredible luck, we could win something tangible, like $20-$30.
Back to the topic, is it
gambling, when we play, say, a roulette inside of a game, where no real money involved? I think it's not. Just as killing inside a game isn't real killing.
