content: This post is not about pleasant and friendly, it is about rising to a challenge and overcoming your fears. Most people fear the command line and seek out the pleasant and friendly. as you say. After completing the challenge you won't fear the command line any more, you will be able to go and install Linux at your leisure, having confidence that if something goes wrong you will know how to deal with it. I would have never been confident enough to install Arch as my primary system without the confidence this little game has given me.
