This is not a complete list, but it's all the tournaments and sources for house games I'm aware of. Most of these are in North America as that's where I have the most info for, but I've included the international games I'm aware of. If you know of a tournament, regular house game, or diplomacy club that isn't included, leave a comment or PM me and I'll get it added!

House Games and Clubs
(These are groups that organize house games, some more frequently than others)
Australia/NZ: http://daanz.org/email_zines.htm (mailing list)
Bay Area (San Francisco-ish), USA: Bay Area Diplomacy Association
Chicago, USA: Windy City Weasels
Connecticut, USA: They don't have a snazzy name, but Hunter Katcher is their organizer and the snazziness of that name kinda sorta almost makes up for it.
Detroit, USA: Another group without a snazzy name. Contact Durga on here or on Webdip for more info (probably have better luck on WebDip).
London, England: London Diplomacy Club
Netherlands: Yet another group without a snazzy name, sheesh.
Ontario/Quebec, Canada: Some of you are just really averse to snazzy names, aren’t you?
Washington, DC: Potomac Tea and Knife Society ([email protected])
There’s stuff in Vancouver, Canada. PM me for Chris Brand’s email if you’re interested.
I've heard there's stuff in Colombus, Ohio, but I haven't been able to track down any contact info or a meetup or something like that for them. If you can find a way to do so, Tom Haver is probably the person to talk to about that, but I don't have contact info for him.
If you’re interested in playing FtF but you’re not sure how to get in touch with people, Cisco spark is a very useful tool. It’s a persistent chat platform where a lot of FtF organizing happens. PM DQ on Playdip with an email address and ask him to add you to the spark, and I’m sure he’ll be happy to oblige!
If you know of more tournaments that I've missed or house game groups that I haven't included, tell me! My hope for this list is to make it as easy as possible for people to find a game if they're interested in playing.
