What the developers have to say:

Why Early Access?

“This is a one-man project that i have been developing on my own for many years now. The game is quite complex for one person to manage and has a very large scope combining things like multi-player, city building, procedural worlds, battles and 4X elements...
I now feel the game has enough content to be enjoyable to play, but it still has too many issues and lacks polishing to consider it a 'finished' game: this is why i decided to make it an Early Access.”

Approximately how long will this game be in Early Access?

“Development on this game will continue as long as I can keep it going, and its ambitions will be readjusted based on the game's reception.
The line between Early Access and effective release is therefore blurry and hard to define. Once i believe a sufficient quality standard and stability has been reached, i'll move out of Early Access.”

How is the full version planned to differ from the Early Access version?

“Please note that this being a one-man game, it is unlikely it will ever reach the quality standards of most other 'indie' games being developed by teams of several people, let alone of professional games.
The first official full version will probably still have many issues.

If the game encounters enough success to gather a community and sustain myself, i plan to continue its development even after ending the 'Early Access' and to work on currently planned 'major updates' adding new content and gameplay such as: factions, religion, culture, immigration, multi-architectural styles, naval, waterworks, additional ages, AI players and modding support.”

What is the current state of the Early Access version?

“All the core gameplay mechanics are functional ( construction, diplomacy, events, techs, economy, battles, worldmap, multiplayer... ).
The game currently covers roughly periods from the Stone Age to the Classical/early medieval Age.
It includes about 200 buildings, 130 unique resources, 170 technologies, 7 'biomes' and 60 different units.
The client and server lack debugging and optimization and many UIs lack polishing and more detailed informations to make the game experience more intuitive.”

Will the game be priced differently during and after Early Access?


Why is it this expensive ?
Ymir is a niche game, and as such it means a smaller potential public, so a higher cost per game. I've also been working on this game for a very long time: started in 2011 and as a full-time activity since 2014.”

How are you planning on involving the Community in your development process?

“I will be using the Ymir Discord to gather and discuss feedback.”

Patch! (and more servers coming)

It’s been a rough week. Never had so many urgent things to deal with at the same time…
For the next weeks, i’ll probably be focusing mostly on server management, stability, and bug fixing, so don’t expect new exciting features for a while.

Server and client bug fixes
Here is finally the first patch of fixes following the release, with mostly server related things.
Notably it fixes the 2 infamous issues of the primitive tribe claims, and the carriers engaging enemies.
Barbarians activity in Solo and Realtime was also reduced.
Server can now auto restart on error, which should reduce downtimes greatly as well and increase the quality of life.
Next step is to find a way to do an emergency save when there’s an error, to avoid the weird ‘rollbacks’ that happen on error.

More servers
Besides that, I’ve been started renting a professional dedicated server. All official servers will be moved to it shortly, and a new ones will be started (offical 5 or official 1 ).
The previous official 1 is renamed Official test server, and will remain on the Tester branch, running on my own home server.
Official servers will now be located near Dunkirk, in the north of France, which is also near the Atlantic internet cables if that helps! 😀
I should be able to run eventually up to 8+ on that dedicated server, with much better performances than with my laggy home server. I hope it will reduce ping timeouts and connections issues greatly.

Worldwide lobbies to see all servers
It was also discovered that steam lobbies were filtered by region by default, which is now fixed and will allow users to see all servers worldwide , especially the official ones for people outside europe.
That will reduce the issue of server shortage especially for players in the Americas.

And lastly, it didn’t take long for piracy of the game to spread. I thought i’d have more time 🙂
That can never be avoided, however the fact that pirated copies can access legit servers is a big issue, and this one can be fixed.
I’ve been working on it for the past 2 days and a fix for that is coming – although not on this patch yet .
I will increase measures to counter piracy with additional checks.
Eventually every player will probably need to authenticate its game at least once in online mode. Offline mode should of course still be possible.

– errors on client now invisible, and dumped into an error folder in the “cache\logs\client\error” folder.
– errors on server now silent and combined with an immediate auto-restart, improving uptime ( also dumped in “cache\logs\game\error” )
– server list will now show all worldwide servers and not only the regional ones
– lowered realtime respawn timer to a base of 10 min instead of 1hour
– fixed exploit allowing to claim tiles of primitive tribes
– added popup warning when attempting to move primitive tribe when starting
– added configurable autosave frequency in server ini files
– reduced barbarian activity in solo and realtime, less frequent and slower difficulty increase
– fixed issue of own character showing up in diplomacy menu
– fixed pathfinding issue with buildings, in battles
– fixed battlecode error on server
– primitive tribe rebellions: fixed primitives deploying inside defensive zones
– “stand ground” units will switch en “engage” if fired upon by range units in same defensive layer
– fixed infamous bug of carriers being in “engage” mode in battles ( and hunts )
– fixed speed settings icons not combatible with CJK font
– fixed some localisation issues
– fixed multiple server side crashes
– fixed crash on worldmap when worldmap quality at minimum

Better late than never: Ymir is released

Last night Steam finally approved my build - the same build they denied yesterday - and i'm finally allowed to release it!

So here it is: Ymir is finally available on Steam, one day late, but better late than never, and at least the week-end is not over!

About servers: I predict the next days will be quite eventful with the influx of new players. Please be patient! It will take some time probably for the community to get more servers going, and depending on the success of the game i'll look to rent proper servers to host more Official servers and accomodate more people.

One of my top priorities is now to work on my own master server to list open ymir servers, replacing the steam lobbies system and to allow for proper steam independent dedicated servers (which is somehow not currently possible to do on the engine i'm using ), which will help having more servers.

About This Game

Ymir is a 4X multiplayer strategy game combined with a city builder where each player develops a civilization of Pigmen starting at the stone age.
The game is divided in 2 main interfaces : a worldmap view and a regional view. Each world tile matches a unique procedurally generated isometric zone that can be explored, settled and built on by players. In each one players can find random resources such as ores , animals or plants depending on the climate, relief and vegetation of the region.


  • Pigs with clothes.
  • Multiplayer on local or persistent servers.
  • Complex socio-economic simulator for a challenging city-building experience on its own.
  • Technological evolution with hundreds to techs, from the stone age to post-iron age.
  • Fully procedural worlds where each region is random and unique.
  • 7 biomes, each one with its own specific resources to encourage player-trading.
  • Advanced diplomatic and economic tools to setup treaties ( right of passage, taxes, payments, trade agreements... ) and trade routes between players.
  • Real-time battles.
  • WILL remain free of any pay-to-win .


  • No direct control over population and economy: They breed, age, work and buy things according to the simulation.
  • Population divided in social classes with specific incomes, purchasing power and revenues.
  • Dynamic resources prices based on supply/demand, rarity and production costs.
  • Even player consumed resources are taken into account: materials for buildings have to be bough at their market prices, generating incomes to the producers and affecting the economy.
  • A simulator instead of a set of independent game rules : all variables and actions influence each other in sometimes unpredictable ways that makes things frustratingly challenging.
  • Producing too much of something can be as damaging as not enough making the logic of the game quite different from classic management games. ( ex: instead of having positive effects, distributing a new resource can actually destabilize your economy if you're not careful )


  • Real-time battles are not instantiated and actually take place in your cities.
  • Build and customize your fortifications with walls, bridges, gates, stairs, towers and battlements.
  • With the terrain tools, modify the terrain heights to take maximum advantage of natural defenses like cliffs and hill tops.
  • Water forces troops to embark and cross with slow vulnerable rafts: dig canals around your forts, secure your bridges or build a citadel on a river-island with fortified bridges.
  • A Strategic-tool allows players to design their local defensive strategy in each one of their cities in case of attack: creating defensive zones, setting troops initial deployment positions and setting their behavior in battle.
  • Battles are not instantaneous and belligerents can send reinforcements while a battle is still in progress.
  • Battles can include unlimited 'teams' at the same time, each one fighting according to its allegiances.
  • Battle troops during a battle are all AI controlled ( so that battles can happen independently of the player's presence ).
  • Dozens of unit types including mounted camels, elephants and armored mammoths.

Main game modes

  • Real-time mode : a 'classical' mode to be played alone or with a few friends, meant to be played with the permanent presence of all players and to be stopped/continued over several playing sessions.
  • Persistent mode : a more "MMO" mode where the game server is to be left running 24/7 at all times even when players are offline and where actions take much more time than in the real-time mode. Meant to be played with the maximum number of players on a day-to-day basis, with games lasting several weeks.


  • This game is a one-man project: development is slow.
  • This game is likely to forever remain an experimental work-in-progress and to never reach the quality, stability and optimization of a finished product: buy it only if you think it's worth it NOW, and not based on future expectations.
  • Playing solo is possible, but the main focus of this game is multiplayer.
  • The game is available in more languages than English, but localization is done by the community and might be partial and incomplete.

    • OS: Windows 8
    • Processor: Intel core i5
    • Memory: 4 GB RAM
    • Graphics: AMD Radeon HD 7800, screen resolution 1920x1080
