Games like Caesar III
Caesar III came out in 1998 and the genre has been measured against it ever since. That is a strange thing to be able to say about a twenty-eight year old game, and it is worth understanding why before picking a replacement.
Caesar III was not the first city builder and it was not the most complex. What it had was a particular idea about how a city should be simulated, and that idea has never really been improved on.
The idea is the walker. You build a road. You put a building next to the road. A person comes out of that building and walks. What they pass, they serve. A prefect walks and the houses he passes stop catching fire. A market trader walks and the houses she passes get food. Nothing is delivered by an invisible hand and nothing is a global number, so every service in your city has a geography, and every failure has a location you can go and look at.
That is why the game is still difficult in a way modern builders are not. When something goes wrong in Caesar III, the answer is never "add more". It is "look at where the walker actually goes". Road loops, dead ends and the placement of a single building are the whole game.
So the question is not really which games are set in Rome. It is which games kept the walker. Here is the honest list.
Caesar III itself, via Augustus
Start here, and start with a port rather than the original.
The game is on GOG for a few dollars and it does run, but the 1998 build is 640×480, windowed awkwardly on modern displays, and carries every interface decision of its era. You do not have to put up with that.
Augustus is an open-source reimplementation of the Caesar III engine. It reads your original game files, which you still need to own, and gives you widescreen resolutions, a zoom, roadblocks, better mouse handling and a long list of quality-of-life fixes the original never got. It is free, actively maintained, and it is the version to play in 2026. Julius is its stricter sibling: the same porting work, but deliberately faithful, with no gameplay changes at all. Pick Julius if you want 1998 exactly, on a monitor that works.
This is the rare case where the twenty-eight year old game genuinely is the best answer, because the community rebuilt the parts that aged badly and left the design alone.
Pharaoh: A New Era
The closest thing to an official modern Caesar III, wearing Egyptian clothes.
Pharaoh (1999) was Caesar III's engine moved to the Nile, with the flood cycle added, which gave the map a clock and made planning around a rhythm the core of the game. Pharaoh: A New Era (Triskell Interactive for Dotemu, February 2023) is a full remake: the same systems, rebuilt art, modern resolution, and the interface repairs the original never received.
If you want the Caesar III experience with nothing to configure and no community patches to install, this is the recommendation. The walkers are intact and the difficulty is intact. The only thing you are giving up is Rome.
Caesar IV, and why people are lukewarm
Caesar IV (2006) moved the series into 3D and is the direct sequel, so it belongs on the list, but it splits opinion sharply. It is prettier, the camera is better, and the systems are more forgiving. Whether "more forgiving" is an improvement depends on whether the punishment was the point. For a lot of Caesar III players it was.
Nebuchadnezzar
Nebuchadnezzar (Nepos Games, February 2021) is the most serious attempt at a genuinely new game in this tradition rather than a restoration of an old one. Mesopotamian setting, walkers, real supply chains, and monuments you lay out block by block instead of watching a progress bar fill.
It is smaller and drier than Caesar III, and its interface asks more of you than it should. It is also the only modern game on this list that is trying to advance the formula rather than preserve it, and the monument building is genuinely its own idea.
Zeus: Master of Olympus
Impressions made Zeus in 2000, two years after Caesar III, and it is the friendliest game the studio ever shipped. Four years of learning what frustrated people went into it, and it added a mythological layer the genre has not matched since: gods who visit your city, heroes you house and equip, monsters that have to be killed.
If Caesar III's difficulty is what you want, Zeus will feel gentle. If the walker simulation is what you want, it is the same engine lineage with better manners. We wrote about it at length in games like Zeus: Master of Olympus.
Cities of the Aegean
This is our game, so weigh what follows accordingly.
We built it because we wanted the Impressions loop in a browser tab, with no launcher and no install. It is Greek rather than Roman, and it keeps the part of Caesar III that matters: roads carry walkers, walkers carry goods, and coverage is geographic. Farm carts haul wheat to granaries, agora vendors carry food out to houses, household foragers set off when a pantry has been empty too long. Houses climb from huts to estates as water, food, oil and wine reach them, and fall back down when a supply chain breaks. The classic failure is the Caesar III failure: a district starving next to a full granary because nothing walks to it.
Some of it is not borrowed. The year runs in four Mediterranean seasons, and summer is the dead season, so banking a surplus is a real strategic problem rather than a background number. Six rival cities sit on an Aegean chart, trade at their own prices, demand tribute, and fight each other whether or not you are involved, so a neighbour you ignored for thirty years can arrive having swallowed two others.
What you should know before clicking: it is a browser game, it runs on your machine rather than a server, there are no timers and nothing to sell you afterwards. It is also smaller than any boxed game on this list. If you want a hundred hours of campaign, Augustus and Pharaoh are the honest answers.
Found a polis on the Aegean. Roads, walkers, granaries, and six rivals who do not much like each other.
