Settlers of Catan

When my wife and I were going to be missionaries in Kenya in 2002 we went to a missionary training place called MTI in Colorado.  At MTI we learned a new game called Settlers of Catan.  All I remember about that first game was something about ten points and that it was over before I knew it.  It seemed okay, but I never knew how great a game it would be in my life.  Die Siedler von Catan was brought into this good earth as I was graduating high school by a German named Klaus Teuber.  When you think of smart German people maybe you think of all the smart theologians like Otto Eissfelt, Gerhard von Rad, Martin Luther, and Dietrich Bonhoeffer or musicians such as Bach, or the obvious Albert Einstein.  But Klaus Teuber deserves a second look.  Here are some unwritten Catan rules that you will not find in the rule book.
1.  Double sevens - don't count the seven until you roll it twice.
2.  Announce other people's points, and overstate them, but never mention your points.
3.  Don't get mad and throw pieces all over the place - you will get mad.
4.  Don't trade with Danny - this is not a rule that I endorse at all, but it has been stated.
5.  Try to get a variety of numbers on your first placements - 4,5,6,8,9,10.
6.  Eat popcorn while playing.
7.  Don't let Danny eat all the popcorn - again, this rule is terrible, but it has been said many times.
8.  The winner is the one who makes the best deals - that is the secret.
9.  We built this city, we built this city on ore and wheat - should be sung when building a city.

10.  Don't let Danny sing the Amish Grandma song - again, horrible rule, who is making these up?
