Soo, es ist mal wieder Freitag!


Welcome to the 32nd Development Diary for Europa Universalis IV and this time we give you the juicy details about how to make the most fun aspect of the game more accessible to all players. And nothing is more fun than playing with your friends, and conquering their puny empires with mighty Ulm.


New Network Code
The old network code that served our games for many years has been discarded. We are now running on Steamworks, and this gives us some advantages. For example, this code supports NAT punchthrough, so you no longer need to open ports to be able to play with your friends.


Hotjoining
One major complaint we've had about the multiplayer experience in our previous games, is the hassle with having to rehost if someone loses their connection or wants to join the game at a later time. We have rewritten our network kengine from scratch and, if the host so desires, players can join a game already in progress through what we call hotjoin. That player will then connect, and get the savegame sent to him or her, allowing that player to join with minimal work, and with just a small pause for the rest of the players.


Matchmaking
Since we have changed our network code, this means we had to retire the use of the old metaserver. EU4 uses Steam’s hosting system, where you'll see games hosted, and you can chat with anyone else in the global EU4 lobby.

Through this lobby, you can invite one of your friends to join you the server you are already playing on or into your singelplayer game.

In the matchmaking lobby you can see what your friends are doing and, if they are playing EU4, you can ask to join their game.

If you like, you can choose to list your server on the public server list where everyone can find and join it. It is possible to add different meta data to the server, such as server name and tags, that are then searchable in the server list. It is also possible to password protect your server.

There are no technical differences between a singleplayer game, and a multiplayer game. So if you are playing a singleplayer game, you can easily turn on hot-join and allow your friends to join it. You know, once you built up a considerable lead.

Standalone Server
As is the case with all serious multiplayer games, EU4 comes with the option for standalone servers. This program allows you to run an instance of EU4 that is simply a server of game-mechanics with no graphical interface, or player playing on it.

This server can, of course, be configured to be password protected and whether it should be visible to the matchmaking servers or not. What makes it more flexible is that you can define who can play certain countries or if only a set of countries is available or not. You can set the names for your saved games and the frequency of the autosave from this file.

You can also set your server to boot up the lobby at a certain time, and then start at another time, and finally end at a certain other set time. When it reaches its endtime, the game will also be saved to the set filename. This allows you to schedule games with precision.

You can also set the start date for the game and give it permission to pause if there are no human players currently active in the game.

Our goal is to have a few servers running constantly for people to join in, to play a country for an hour or two, to have the fun and crazy experiences that multiplayer veterans have become familiar with.


Improved Chat
Eu4 has an improved chat compared to EU3. We are using the one we premiered for HoI3: Their Finest Hour, where you can have chat channels and secret whispers. It also has a long scrollback so you can see all the previous chat, and is easily minimized so it won’t obstruct the screen while playing. You can also clearly see when a private message sent to you.


AI Takeover.
As all who have played a game over the internet can testify, shit does happen. Sometimes you lose your internet connection, sometimes you lose power, sometimes the game even crashes. In EU3, the host could then decide to have your country either go braindead or become fully controlled by the AI. In EU4 we have expanded this, and now have a few options where you can tell the AI how they should govern the country while the human player is AWOL. You can tell it to avoid starting wars, to keep alliances even if an AI would cancel them, whether it canmove merchants or not and more customization options.

What is also cool is this aspect is saved in the save game file, so if you miss a session in your MP campaign, your country is more likely to be as you want it when you get back to playing it again.

Das mit dem Hotjoining gefällt mir. Das es Steam ist weniger, vermutlich werde ich, wieder wegen EU, etwas ändern müssen. Bei EU3 musste ich nen neuen Rechner kaufen, hier also dem Teufel Untertan werden. Sei es drum...

Siehst du Abo, war nur eine Frage der Zeit bis der Beelzebub endlich ein Spiel exklusiv veröffentlicht, das auch du unbedingt haben willst. :D

Willkommen im lauschigen Steam-Club. Bei uns gibts auch Schoko-Cookies. ;)

Ich kauf es mir eh noch nicht sofort, aktuell spiele ich auch kein EU3, verplempere meine Zeit mit Arbeiten und Familie... haha, Scherz, natürlich mit Bloodbowl, STO und Anno 1404. Ich sollte mal wieder fürs Studium lernen...

Ich hoffe doch, dass es wieder einen LAN Modus geben wird

Nachdem ich EU III Chronicles gestern wieder installiert habe und nun von dem Nachfolger erfahren habe, bin ich doch sehr angefixt.
Wie siehts denn aus, gibt es bereits einen genaueren Termin als Q3 2013?

Nicht, dass ich wüsste. Glaube auch nicht, dass Paradox sich da selbst zu früh festlegen will. Das Spiel ist fertig, wenn es fertig ist. Ich rechne aber fest damit, dass sie es zum Weihnachtsgeschäft spätestens auf den Markt bringen werden.
