5. “To play a game is to engage in
activity directed towards bringing
about a specific state of affairs,
using only means permitted by
rules, where the rules prohibit
more efficient in favour of less
efficient means, and where such
rules are accepted just because
they make possible such
activity…playing a game is the
voluntary attempt to overcome
unnecessary obstacles.”
