I pondered what it would be like to have people play Oak Games-style
games in a higher-end coffee shop for one day;
a typical Steve fantasy.
People win prizes when they win games against strangers.
I would not have brought this to your attention except for the social effect.
Instead of people being isolated or focused on their phones, you could show up, likely with
a friend or two, and there would be face to face
playing - and/or coffee drinking. There would be an incentive to deal with strangers.
This would not be structured, not a tournament, and games would not always merit prizes.
You don't have to know the game rules before you arrive. These games have simple rules.
