1. You have plenty of time to chat.
2. A fun activity. A little athletic, you can show of your skills but not too athletic you don’t leave sweaty.
3. You can tell a lot about the person your with by how you play. (Does he let you win? Does he let you cheat? Does he keep score? Is he super competitive? Do you have fun?)
Not that any of these are applicable to a relationship but they are interesting to know.
