Thanks for the comment, Leethe. (I saw your project this morning and I was intrigued. I plan to check out your demo tonight.)
As you said, my project is certainly not very linear, but it will likely play out more linearly than it first looks. Each night is a tree of branching paths, but you always advance to the same next day (I picture it like an orchard of trees that you visit in order, and you can pick one piece of fruit from each. If that makes any sense). Your stats will have an impact on the day (like whether you snap at your girlfriend and hurt the relationship), but it won't change the contents entirely.
Goto macros are indeed great at avoiding clutter, but I hadn't thought of using if:false to draw fake arrows. That may prove useful later!
