Immerse yourself in the fascinating world of the Roman Empire and build your own ancient metropolis! Pax Augusta is probably the most authentic city-building simulation set in the ancient world and puts you in the role of an ambitious governor who builds new cities along the Roman borders.
While Emperor Augustus expands the borders of the empire, capable governors are sought to found new cities in order to consolidate the Roman claim to the newly conquered land. You build a small settlement along a newly constructed imperial road. You attract new inhabitants to the city by building a harbor and a forum.
As your tax revenue increases, you start to mine raw materials and construct new buildings to meet the needs of the population. Baths, theaters, gladiator schools, slave markets, and more serve not only to keep your inhabitants entertained, but also to provide them with work.
Build impressive city districts, ensure the well-being of your citizens, engage in flourishing trade and erect magnificent monuments that will last for centuries. But the road to the top is full of challenges - fire, corruption, unrest and the whims of the emperor will put your leadership skills to the test time and again.
As a skillful governor, you will quickly attract the attention of the senate or the emperor. Increase your reputation enough and you can found new settlements. As you increase your private fortune, you will eventually be able to afford to apply for new offices. This gives you the opportunity to build monuments and unlock new building sites.
Will you become a skillful administrator and make your city flourish? Or will you fail and be deposed by the Senate?
Your skill will decide your fate in the most powerful empire of the ancient world!

Pax Augusta for PC starts at €3.94 at Difmark, 84% under the €24.99 of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €6.65 at Difmark Digital Keys.
That €3.94 already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
The cheapest one listed, €2.99 at Instant Gaming, is out of stock. The cheapest you can actually buy today is €3.94 at Difmark.
With 23 offers across 12 stores there is enough competition for the price to move, so the gap between the cheapest and the rest is worth checking before you buy.
That puts it 3% under its average of €4.08 since 2025, so today is a better entry point than most days of its life.
That €6.65 key is expensive for what it usually costs.
Worked out from 1,667 daily records of the Steam Key for Pax Augusta across 13 stores. See the full price history.
The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
With the shared account at Difmark you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.
The key at Difmark Digital Keys costs €2.71 more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.
The 5 Steam Gift offers are pricier than the key and leave more room for error, because they depend on the region and on Steam friendship.
17 of the 23 offers work on US — the Global ones plus the ones issued for your own region.
One listing is worth ignoring: the Steam gift that G2A has at €26.34 is more than 6 times the cheapest offer and is not what this game costs. The number to work from is €6.65 at Difmark Digital Keys.
Outside of the gameplay elements, Pax Augusta delivers on its promise of helping aspiring leaders build the Roman city of their dreams. Going from humble... Read more
