"A factor of chance" does not make a game "unworthy". Particularly, you're looking at this as a binary decision of worthy or unworthy. What makes a game interesting to most people is how much randomness there is. Human brains are built to dole out reward hormones when they make predictions and, followed by a period of uncertainty/expectation, their predictions come true; OR fail in such a way that they gain enough information to improve future predictions. Having too little randomness can (if there is little complexity) mean that predictions always come trivially true, which does not trigger the reward mechanism. Having too much randomness disables the triggering by way of a "teaching failure". (Though it still leaves the way open for the success trigger, thus addictions to gambling.) So in order for a game to be good, it needs to strike a certain balance between simplicity/complexity and determinism/randomness.
