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.”

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.

Release delayed: Steam has denied the game's release

Yesterday Steam denied my current build for release, and today i'm therefore unable to release my game as planned, until it gets approved.

The reason given for this denial was that according to them "the game does not appear to currently support online gameplay ", yep, that's right.
Despite the fact that after more than a year in closed testing hundreds of players participated in games (mostly online), in multiplayer, and that as i received this reply the current test server i'm running myself had players online...

Now before i go on I must say that this also happened because i made a really bad mistake. I had so many things to deal with the upcoming release, that i didnt realize in time that i had to send a build for manual review and approval before being allowed to release. I wrongly assumed that releasing was automated (like pretty much everything else) and a formality that wouldnt take long like every other steps i had to pass before, especially as everything was ready. But i was wrong. This was the ONE of the few things that had to be manually approved by actual people.
When i realized it about 3 days ago, it said that it usually took 2 to 3 days to approve (but could take more if there was issues), so I hoped for the best and submitted it only to receive a negative answer yesterday night.
Of this i am totally responsible, I should have realized this before and started this earlier. Considering things now... apparently weeks before the release date!
This is my first game release, so i'm learning here and making mistakes, espcecially as being alone to manage so many different things and where an error in a single one can make everything else fail - as it now did. For this i apologize to everyone.

But i have to say you'd be surprise how even as a dev, we have pretty much zero human contact with anyone from Valve either. Its more of a self running website where all you're left with is some documentation and a forum of other devs trying to figure out things themselves too and sharing experiences. You can't get any help, and the whole steamworks interface is very confusing, sometimes even faulty/buggy, which doesnt help to make things intuitive.
Is there still humans working at Valve ? nobody knows. I personnally suspect Gabe merged with the mainframe "lawnmower man" style years ago, and left us all to despair with this platform.
More seriously, the ONLY way to contact anyone human at Valve is to send... a support ticket. To which you'll eventually get an anonymous response of about 12 words -at best-, after a day or more. When i realized my mistake i did that. Luckily i got a one line answer - as is tradition - saying they'd speed up the process, but only to receive this absurd denial an hour later.
And the denial explanation was the most cryptic part: " we found out that the game is using the public IP instead of the IP4 address which the port is open for. This happen with hosting only a server form the localfolder. "
If anyone understand the meaning of this sentence, please give me a call.
What is this rambling about the 'public IP' when for an online multiplayer game, that's what it should be using to allow others to connect... online, rather than using a local IP only reachable via LAN ?
What is this thing about 'instead of IP4 address' when all IPs ARE in IPv4 format ?
ANd what the hell does " hosting only a server from the localfolder " even means in this context ?
Nobody knows.
Apparently not only did these testers failed where hundreds of testers have never had trouble doing so during over a year of tests (which is to simply join an existing server), but they ignored the visible public server showing online players at that very time, and concluded that surely that must have been an illusion and that online multiplayer did not exist in this game, while giving the most absurd explanation that made zero technical sense to me.

And as it was an anonymous message with no way to reply directly, that means being back at square one, having to resubmit, and wait again 3 to 5 days. I have no way to ask these specific guys what the hell did they mean or tried to do.
Worst of this is that i don't even know what to change , considering their reply made no sense, so i just ended up resubmitring the exact same thing... with one minor change: i removed the "online multiplayer" tag as it's apparently what triggers them, adding insult to injury for a game that is mainly... online... and multiplayer.

So here i am now, on release day, unable to release my game after about 8 years of work.
Big AAA city builders games are about to be released in a week or so. I had the perfect release day planned, and now it's ruined.

But even though it's partly my fault, i can't keep but feeling bitter at the lack of understanding from Valve's side. On one hand because they didnt seem to care that denying me this for some absurd reason ruined such an important day for me, and on the other because i can't help but feel infuriated that somehow my game was under greater scrutiny and had to meet high quality standards( resulting in a denial), when in the meantime the cheapest porn games and asset flippers seem to be released on a daily basis without the slightest oversight on steam. Like...really Steam? MY game gets its release denied but those are fine?

So what now ? Well i'll release as soon as i can. I don't know when that will be now. I can't do anything else right now but wait...

Best case scenario it sill somehow happens today.
If not its probably over until at least Monday as this will be the week end.

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.

    • Memory: 4 GB RAM
