This is an article I wrote on boardgames subreddit seven years ago, about a tournament game of Diplomacy which had lasted more than 3 years and was still ongoing at the time. It eventually ended in a draw with Italy leading, in Feb 2016, after 3 years and 7 months of play. I'm reposting it here because I'm quite proud of the article (and I want to move it away from Reddit) and because imo it still holds up as one of the greatest events in the history of Diplomacy and a very interesting event in niche internet history.

tl;dr - Seven players (less now that some have been eliminated) have been playing a game that simulates the First World War in a Tournament. They've been playing it so long that the First World War is now continuing on into the 21st Century. The game has been out for 57 years and this has never happened in a recorded game before.

If you are not familiar with Diplomacy, it's a war game based around negotiation where 7 players each play one Great Power in the First World War, attempting to gain control of Europe by taking key provinces known as Supply Centers. It's very similar to A Game of Thrones - The Board Game except that you can (usually) talk in private with other players and all players must submit orders for a phase before any are revealed, meaning that you don't know if your 'ally' will backstab you that phase or not until you've already set your orders. Other players can support your units into provinces, so negotiation is key to victory.

Everyone who knows about Diplomacy knows that it takes a ridiculously long time to play. In a face-to-face (FTF) tournament strict deadlines of 15 minutes per phase are set, and games are played from 1901 to 1908, meaning 4 hours for a game. In casual settings, where the timers aren't observed so harshly, a game of the same number of phases can take 8 hours.

Because of how difficult Diplomacy can be to start in real life, there are a lot of active communities for playing it online. In online play, phases are usually set to process every 2 days, and you only need to dedicate an hour or so a day to it. Because of this, the set end date (1908) used in most FTF games isn't needed, and the game can be played to the win condition stated in the rulebook - one great power controlling 18 Supply Centers - which isn't used much in FTF because it takes far too long to achieve. This in turn means that games can last months.

There's also the possibility of an 'eternal game' since there is no set end date. Usually, this is due to stalemates - there can be positions where no player can push any further forward, and no player can back off because another player can win as a result. These games are declared drawn, since no victory is possible.

However, there's a small possibility of a game that would go on forever while going back and forth, back and forth - one power gaining centers then being pushed back by the others, and then another, and so on, without the game being stalemated. In practice, this sort of thing rarely happens - going by statistics from webDiplomacy last year, out of ~43000 games completed, only 17 had legitimately passed 1930, and none of those had reached the year 1940.

The longest recorded completed game comes from another site and reached 1964 -note, I originally had a link to this game but it appears to now be dead. However, one non-completed game on webDiplomacy completely blows it out of the water.

The 2012 webDiplomacy World Cup Final has one game still ongoing, long after all the others have been completed. This game has just reached the year 2000! That is absolutely insane - if this had been a FTF game at a tournament, the participants would have been playing for just over two days straight. Since it's online, they have been playing for three and a half years.

I have checked with several important members of the Diplomacy community and it is indeed the first game ever to have legitimately done so (not just because some players decided to mess around until it reached that date).

What was/is the 2012 webDiplomacy World Cup?

The World Cup was an event held on webDiplomacy which mimicked the FTF Diplomacy Tournament that goes by the same name. Different countries (or regions, if there were not enough players in a country) would gather a group of players and play in a group of games with teams from 6 other regions, each having one player in each game, and gaining points based on how well they did in each game. The best countries/regions advanced from groups in a knockout style until the Final, which has not yet finished.

Why has it gone on so long?

That's a difficult question to give a straight answer to. It's a combination of several factors:

• These players are insanely good. The teams in question reached the final, and they picked their best participants at the Public Press Variant (which I'll come to next) for this game.

• This game is Public Press Only. That means that any messages anyone sends are received by everyone, which slows the game down a fair amount because players have to position themselves to make completely uncounterable moves if they want to coordinate them with allies, or they have to risk their allies misunderstanding what they are doing and not supporting them correctly.

• Nobody wants to lose or draw. Sounds trivial, right? Everyone wants to win any game they're playing. This one is different, though - every other game in the world cup has finished, so everyone in the game knows how many points all teams have. Every team in this game can still win the overall tournament, but for most of them it is only if they achieve a solo victory. One specific team will win if all players draw, so nobody except that team want this game to end in a draw, and certainly nobody wants anyone else to get a solo.

That said, fatigue is starting to set in and they may draw the game soon just to be done of it. That's only after over 3 years of trying to achieve a solo though.

Do you have a handy graph of how the SC counts of each player have changed throughout the game?

What a coincidence! I just happen to have one right here!

That game is really long. I want to just see the interesting bits.

Again, you're in luck! I happen to have an imgur album here which shows the high points and low points of each great power and explains a little what happened to them. The important provinces (Supply Centers) are marked by white circles with a black dot in them. The provinces and units belonging to each country have an assigned colour as follows:

• Pink, England
• Blue, France
• Brown, Germany
• Green, Italy
• Red, Austria
• Purple, Russia
• Yellow, Turkey

If you do want to look through the game for yourself, you can find the full record here. On webDiplomacy, red arrows represent move orders, yellow arrows represent support move orders, green lines represent support hold orders, and blue lines represent convoys.

Has any Supply Center never changed hands?

No. Every Supply Center on the board has changed hands at least once. Ankara has been taken the least, it's been held by Russia for the 76 years since he took it from its original owner, Turkey, in 1925. Rumania has been taken the most, it's been conquered an astonishing 26 times. Most SCs have been taken around 11 times, but in particularly contested places (like the Balkans and Scandinavia) the average is much higher.

If it's Public Press Only, can I read the messages the players have sent?

Yes! You can find all messages sent in the game here. Use the blue arrows above the messagebox to navigate pages. The chat from each country follows the same colour coding as their provinces and units.

Bear in mind, though, that there are so many messages to look through that they actually crashed the game at one point. The site administrators had to assign more memory to the chat of this particular game to fix it. There's also some profanity in some of the messages, although not many.

Diplomacy sounds interesting. Can I try it?

First off, playing the game in person is a very different experience to playing it online, and one that I find to be much more tense and exciting (although online is good too!). I'd very much recommend you play it in person first. You'll need a copy of the board game (it's available on Amazon) and 6 friends with 4 hours spare.

Obviously that can be a bit difficult to arrange, so you could also look for Diplomacy Face to Face groups in your area - there are quite a few of them around the world. If you want information about them feel free to PM me and I'll try to find out if there are any in your area and get back to you. Also, if you're part of a board gaming group, it's possible that someone there will have a copy so you might be able to play it with them.

If you are interested in the online version, there are many online sites that offer it. I'd recommend webDiplomacy but there are plenty of others if you don't like the interface there.

Is there anything I should know before I play?

Yes, specifically if you're playing in person. I'll let some board game celebrities say it for me:

"This game makes people mad, and I mean really mad." ... "The tagline is 'Diplomacy - Destroying friendships since 1965'." - Tom Vasel

"Diplomacy wounds run deep, and take forever to heal." - Wil Wheaton

It's not quite as bad as they make out, but it's worth making sure that you don't play it with someone you know will take lies and backstabbing badly. Also - don't play it over several sessions, the paranoia you get when you see other players talking to one another in the breaks can be unbearable.

Congratulations if you've read this far, and I hope others found this Diplomacy game to be as incredible as I did!

I've recently been getting into Diplomacy (both face to face and online) and it's surprisingly fun, although requires some dedication. I'm wondering if anyone here has experience with the game or some tips for learning more in-depth strategy? It feels like online resources aren't that great or plentiful yet I'm having a hard time surviving against experienced players.
