Create your cities from a large set of customizable buildings, manage various production chains, negotiate with neighboring towns to trade, define taxes and policies, and watch as Ostriv’s world reacts to your decisions in a natural way.

detailed economic simulation and human behavior
There's a strong emphasis on interaction with your citizens. People in game act like people: they have their own motivation, needs and skills. Citizens will take jobs only if they are satisfied with them (or they are desperate). They can sell goods and services to each other on the local market. Wealthy citizens could start their own business in your town and hire other people. You will need to influence your city by means of setting prices, taxes and various policies. Each decision will certainly lead to some reaction of the society.

- trade
You can conduct negotiations with other cities to conclude the most profitable trade agreement. Explore nearby cities by sending messengers to find more import and export possibilities.

For more effective resource transportation inside the town or for outer trade you will need vehicles. Wagons, fishing boats and wheelbarrows could be built by a local carpenter or to be bought from outside.
The breeding of draft horses and oxen is also required to move resources as well as for cultivation of fields.

unrestricted building placement
There’s no any kind of grid or angle restriction for placing buildings. Any building could be placed on any angle. Building on slopes is also available.

roads modeling
Dirt roads are formed in a natural way at places, where people move the most. You can build paved roads for more comfort and better aesthetics, but they’ll be used only in case of reasonable placement.

For those who somehow didn’t notice, I remind that a city-building game Ostriv is now on closed testing stage. And I have to admit, this was really a damn right decision. A numerous team of testers gathered so much useful information, that would take a year for me to do it alone. Besides, it was a good opportunity to set up all the means for maintaining the feedback and send updates. Sure this will be very useful when the game goes public.

Also I’d like to thank all the testers for investing their time to fill in the application form with really inspiring stories! Yes, I read them all :) Sure it takes a lot of time, but I’m happy to learn so much more about my audience!

Today I’m gonna release patch 8 for testing version of the game and send out 200 more keys for new testing applicants. Meanwhile, let’s see what’s in the upcoming update:


    • Prioritizing closest carts
    • Now resources can also be taken from paused construction
    • Production limits: allows to choose how much of each resource to produce
