I have an idea to create a set of flash cards to test one’s compatibility for friendship. It would be intended for a bout of fun and could be played as a game at a small group party or perhaps with just two people.
In a party situation your date could be unwittingly revealing more about themselves. Ah, a person could shave years off of their life, knowing early on in a relationship that there are deal breakers. It might certainly open up a dialog.
Another idea, is to include a basket of nerf balls with the game. The person with an unfavorable response to the crowd might get nerfed.
