Let's Play the Stanley Parable 05: Stanley Makes Awesome Choices
What were to happen if you no longer had any reference for if the choices you could make were right or wrong, bad or good? In such a situation you'd have only have your own thoughts to guide you and it would be quite possible for you to make all sorts of strange choices.
No matter what kind of choice it is however one thing that hasn't been mentioned yet is that regardless of the type of choice, you will never know with absolutely one hundred percent certainty what will happen because of your choices. In theory anything is possible; you could transform into a teapot mid-way through reading this sentence. Unless teapots are capable of sentience and possess visual senses however then the fact that you are reading this confirms that you have not in fact turned into a receptacle for the storage and pouring of tea. While you shouldn't go through life wondering if you'll spontaneously transform into a kitchen utensil it is something to keep in the far recesses of your mind, just in case. Possibly.
That said, in this video Stanley may decide to do one of the most awesomely awesome things that I wasn't expecting whatsoever.
