Doesn´t work with a top trumps game, because the answer is either yes or no.
We need a value which differs a lot from language to language.

This would be the same as if you write on a car top trumps card game "has sunroof?". It makes no sense, because the chance of a tie is very high.

I´m going to investigate the "standard lib" idea further.
But please keep your suggestions coming, they help me to look at the game from different directions.
