&quot;A factor of chance&quot; does not make a game &quot;unworthy&quot;. Particularly, you&#x27;re looking at this as a binary decision of worthy or unworthy.<p>What makes a game interesting to most people is how <i>much</i> randomness there is.<p>Human brains are built to dole out reward hormones when they make predictions and, followed by a period of uncertainty&#x2F;expectation, their predictions come true; OR fail in such a way that they gain enough information to improve future predictions.<p>Having too little randomness can (if there is little complexity) mean that predictions always come trivially true, which does not trigger the reward mechanism.<p>Having too much randomness disables the triggering by way of a &quot;teaching failure&quot;. (Though it still leaves the way open for the success trigger, thus addictions to gambling.)<p>So in order for a game to be good, it needs to strike a certain balance between simplicity&#x2F;complexity and determinism&#x2F;randomness.
