Part 5 may potentially be the last part of this series, due to me being pretty bad at the game and not fully enjoying it. I'm willing to keep going with it if enough people want me to, but I've provided a list of alternatives in the description of Part 5, and I'll be looking at posts there to determine what to do next.
