Thanks for the feedback. I swear the whole time I was thinking "make sure you get the right planes", bit daft I ended up messing that up anyway. Thanks for the feedback on the clarity, I'm quite relieved that it's ended up that parseable , I was a bit worried about that
Regarding the second map thing, the idea I was angling at was that the "tree of life" diagrams that each player builds over the course of the game were the second "maps". I did make sure to check that people had described them as maps and as far as I can tell, they are. Perhaps I should have made that more explicit?
Good point on the arm wrestling. I think at that point I was thinking "There's already a couple ways to resolve this above this that could fail, I don't want to bog people down in another layer of 'if that doesn't work, do this' so I should put something interesting in at the end" but I probably could have chosen a better one.
