Most of the games I play, they fall into at least one of the following categories:
Cooperative - where everyone playing either wins or loses together;
Historically or culturally significant - with ties to the values of a particular time or place;
Aesthetically beautiful - with visuals that could be described as art;
Relevance - where the trappings add to the cultural conversation of modern life;
Mind altering play dynamics - where we are forced to think in new ways.
