Hello. :)
There was a diplomacy World Cup hosted on stabberfou, but, from reading, it was faffing about heavy and getting good teams together light.
How to organise a tournament?
1. You need to come up with a viable tournament structure.
--Straight one game Knock-outs don't really work that well because you have lots of trouble with draws.
--Any structure must have a good points system.
--It mustn't take too long. You probably cannot have that many rounds.
If I were doing a world cup, it would run something like this:
Leagues Stage- groups of seven, top 3 or 4 go through from each League
or Knock-out Stage- rather like an expanded GFDT round
followed by either another Leagues/Knock-out stage if there were many different countries, or just by:
final- seven teams, each player from each team plays a game (like the World Series will be if it gets off the ground)
But don't take my word as law on this if you can think of something better.
2. Publicise it. Particularly for a team event, you'll need plenty of exposure to get it running. To give an idea, the Leagues went something like this:
First Season (Summer 2008): 14 players
Second Season (Autumn 2008): 42 players
Third Season (Spring 2009): 77 players
Fourth Season (Autumn 2009): About 80ish players.
Being made public without much effort on my part, or anyone else's, but rather by having people just mentioning it.
On the other hand, the for the Masters I had over 50 people straight up because I plugged it pretty heavily to the league mailing list and on the forum. For a World Cup to work, you need lots of people, so you need to plug the idea when you've got one.
3. Be patient. You will be surprised how many people don't read things that you post, don't follow instructions properly, or read the weirdest shit into what you say. When I asked for masters emails to be sent to a particular address, I got them arriving in:
My personal Account
The Mod Email
on the Forum
Via MSN, Gmail Chat
Via PM
and In-game
4. Make sure you have some evenings spare to really get your head down with organising stuff.
But that above does make it sound more difficult than it actually is. I hadn't run a tournament before the leagues, and just followed my nose; I don't claim any special sense of smell.
