Greetings, Tyrants!

You have waited patiently and now, the time has finally come. V71 Reign of Terror is now available. V71 is about law, order, slavery and family. Keep your population loyal through fear, or bring them happiness instead through mercy. The choice, as always, is yours.

To mark the occasion, poor Bob is back. You thought him dead on the battlefield, but alas for Bob, his gods were not that merciful. I hope you enjoy his unfortunate tale.

The Sacrifice of Bob Part II: The Enslavement of Bob

I write it at the end of this post, but I will mention it here as well: As usual... the update became much larger than I had planned on. There was a longer closed testing phase to make sure I managed to fix bugs and balance. But if you still find issues please go to the Discord and report them. I will spend some time after the release to fix bugs and balancing.

MAIN FEATURES

REIGN OF TERROR

Keep control and inspire loyalty in a population that fears you. Punish the disloyal with methods only those strong enough to rule would consider. Slavery has been reworked from the ground up, with slaves now becoming both a special type of subject and a fully tradeable good. Their fulfilment and happiness now work more or less exactly as they do for citizens.

If your subjects grow unruly, station guards to patrol the streets and impose order. Or be merciful, and focus on happiness instead of loyalty.

LAW AND ORDER

Law has been completely remade, and is now primarily about trading happiness for loyalty. A utopia with full happiness needs no law at all, and you can play the entire game without touching any of it. But ruling is rarely that clean. You dictate a punishment for every crime, and each crime and punishment affects happiness and loyalty differently. Guards, guard post coverage, execution places, secret police and more all multiply these effects.

Invest deep into law and the returns become exponential, opening the door to full tyranny: forsake happiness for absolute loyalty and build your dystopia. New guard rooms radiate an aura that improves law, gallows are now simple placeable items worked by your guards, and a dread aura helps keep the rest of your subjects in line.

FAMILY AND LEGACY

Most races now have children naturally, replacing the old breeders. Parents care for their offspring at home until they come of age, with education and services evolving to support children while boosting innovation, knowledge and admin.

You can also trace the lineage of your subjects throughout history. A family tree holds up to a million entries, tracking ancestors and siblings, so each subject finally has their own story to tell. The old nurseries have become a single global nursery where children spend their days, lowering child mortality and giving fulfilment to slaves and citizens alike.

TECH AND TRADE RENEWED

The tech tree has been remade once again. Techs are 50% cheaper in general, but common nodes are gone and rooms with multiple recipes cost more, with new consumption technology for each recipe.

Trade has been refactored alongside it. Tariffs now work both ways as a percentage of the goods price, tolls let you sell cheap wares at a good price, and every resource carries a per item price addition to account for logistics. Early trade is more expensive, but in the late game every resource can turn a profit depending on circumstance, and where you allocate your emissaries starts to matter a great deal.

DISCORD, FEEDBACK AND OTHER STUFF

As usual I was overly enthusiastic making this thing. The update became much bigger than first anticipated. As you can see in the patch notes, I have made many, many changes. As a result, we had to have an long period of closed testing.

Still, bugs and balance issues may appear. If so, and if you wish to tell me about any issues, go to the Songs of Syx Discord and report them. I try to read as much as I can.

Also worth noting:

Saves: Your saves will break

Rolling back: You can roll back the update to V70 if you want to finish your run before updating

Mods: Many mods will break. We have invited many modders ahead of time so they can update their mods before the release, but far from everybody. Give them some time to make their mods compatible.

MIDWEEK DEAL 25% OFF

My partner Sterling who runs marketing and stuff insists we have to do stuff like this. So for the first time ever we have a Midweek Deal starting at the same time as we are releasing this thing. The discount will run for 10 days, then we enter the Summer Sale as well. So tell your friends... and all that.

Devlog video

Patchnotes are at the bottom of this post. As usual, I have also made a video log where I walk through all the features. Or so I hope...

Sterling tried to fix the sound this time with a bunch of magical filters. As revenge, I shot the thing in a wide format to give the video that cinematic flair, with black bands on the top and the bottom. I like it. V71 Devlog Video
