Synopsis

Caesar IV is a city-building game set in ancient Rome, where you plan and govern towns across the Kingdom, Republic and Empire eras. You lay out housing, farms, workshops, markets and temples, balance trade and taxes, and keep citizens of different classes fed and happy. Scenarios ask you to meet goals for population, wealth or defense while answering demands from Rome.

Developer: Tilted Mill Entertainment
Released: 2006
Genre: Simulation, Strategy
Where to get it: Steam

Reception

Critics gave it a Metacritic score of 74, praising its deep economy and the move to road-based services in place of Caesar III's wandering walkers. They faulted an oversized, fiddly interface, building effects that cannot be previewed before placement, a clumsy camera, repetitive scenario goals and heavy performance demands for its time. Its online score modes are gone. Players today rate it Mostly Positive on Steam and 4 out of 5 on GOG, where some still find the camera and controls awkward.

2.5/5

Controls feel awkward on a modern controller or mouse and keyboard
Keys cannot be remapped, there is no controller support, and the Ctrl key used to rotate buildings causes interface glitches. Players also report invisible blockages when placing buildings on the fine grid. Source: pcgamingwiki.com, worthplaying.com, gog.com.
Menus, text or interface are hard to read on today's screens
The interface takes up a large share of the screen, the building menu stays open over the map, and service radii only appear after a building is placed. Reviews call these inconveniences a drag on the strategy. Source: gamesfirst.com, worthplaying.com.
Saving is fair: free saves or frequent checkpoints, little lost progress
Cities can be saved by hand during a scenario and the game also autosaves. There is no continue button, so resuming means picking a save from the list, and one player reports that saves can fail after the game sits paused for a long time. Source: steamcommunity.com, gog.com.
It teaches itself: no guide needed to make progress
The first campaign, set in the Kingdom era, works as a tutorial that teaches the basics before the Normal and Hard campaigns. Its early maps are small and fairly demanding. Source: worthplaying.com, gog.com.
Pacing drags: grind, filler or forced backtracking
Scenario goals repeat a handful of basic types, and some win conditions take hours to reach. Reviews note the objectives grow repetitive over a campaign. Source: worthplaying.com, gamesfirst.com.
Camera or movement fights the player
The 3D camera rotates and zooms from street level out to the whole city, but rotating rarely leaves the view where players intend. Reviewers found it tricky to angle the camera onto the spot where a building should go, and GOG players call the view angles hard to manipulate. Source: honestgamers.com, gamerstemple.com, gog.com.
