We The Players...
Let's start thinking big and grand about our game sessions. Let's begin by listing 10 things we believe and can agree upon. If ever these elements come into question, we'll simply point back to our gaming social contract and remind that for all of us to get along, we agreed to these things. Players are enthusiastic people, but without this social contract the precious time we have to play can become compromised by things like: arguments, delays, rules lawyering, metagaming, waiting for folks to show up, and more. The fact is, every gaming table should have a social contract like this one, and it's value to our group will pay dividends in the future. We must all believe in these principles, and stick to them, to ensure the few hours we have to play aren't depleted by negative or unconstructive behaviors. These are the 10 things we expect from players:

6. We know the rules we use.
5. We do not "rules-lawyer".
