There is a huge misunderstanding going on this thread, copyright law does not protect against let’s plays. Copyright protects the original author on the rights to make copies of their work. E.g. Distributing copies of a new song or movie would fall under this.

For me the ending was about whether you would sacrifice your best friend for the world problems. This is what I felt throughout episode 5 and in those terms I ended sacrificing Acadia Bay. I guess that makes me selfish in the real world.
