. What I
am saying is that it is not practical to cover all possible
misconceptions on a stash tube. Just when you make something foolproof
along come better fools.
I don't think this is a particularly useful way to come at the problem. If the final product leaves some obscure ambiguities, fine, but why stat out by accepting them? I see no reason why a game as simple as Treehouse shouldn't be expressed completely, limited space or no. It may be very difficult, but that's why we're all testing and discussing it.
As for creativity on the part of the player, that should always be encouraged, but there's no reason to make the game incomplete in order to _force_ the player to make up their own rules - not everyone enjoys that kind of play. Experimentation and creation of house rules should always be allowed and encouraged, but not at the expense of having a complete game.
