Synopsis

Europa Universalis III is a real-time grand strategy game from Paradox Development Studio covering world history from the late Middle Ages to the Napoleonic era. You pick any of more than 250 nations and steer it through diplomacy, trade, colonization, religion and war on a map of over 1,700 provinces, with no fixed goals beyond the ones you set yourself. Time runs continuously but can be paused at will.

Developer: Paradox Development Studio
Released: 2007
Best version: The Complete edition on Steam bundles the In Nomine and Napoleon's Ambition expansions; Heir to the Throne and Divine Wind are sold separately, and Divine Wind fixes a crash that Heir to the Throne introduced.
Genre: Strategy
Where to get it: Steam

Reception

Critics at release praised its depth, freedom and replay value, giving the PC version a Metascore of 83, and IGN found its interface more polished than earlier entries in the series, though its tutorial left important gaps. On Steam it is rated Very Positive, but recent reviewers call the interface clunky, the mechanics poorly explained and the pace slow, and some point new players to more modern strategy games.

3.5/5

Controls feel natural on a modern controller or mouse and keyboard
Everything is done with the mouse on the map and in menus, and the game can be paused at any moment to issue orders; there is no controller support. Source: pcgamingwiki.com, gamegrin.com.
Menus, text or interface are hard to read on today's screens
Critics in 2007 found the interface more polished than in earlier entries, but players today describe clunky menus that bury basic information, and early players also struggled with it. Source: ign.com, steamcommunity.com, boards.straightdope.com.
Saving is fair: free saves or frequent checkpoints, little lost progress
Campaigns can be saved and reloaded freely, though zoom level and game speed reset after each load. Source: pcgamingwiki.com, boards.straightdope.com.
Hard to make progress without a guide
The tutorial explains the buttons but leaves out key steps, crashes in the Complete edition from the second lesson on, and Paradox advised players not to use it, so most players learn by trial and error. Source: pcgamingwiki.com, gamegrin.com, ign.com.
Pacing holds up: little grind, filler or forced backtracking
With no missions or set objectives, players set their own goals and speed up or pause time as needed; reviewers found campaigns absorbing, though some players today find the long waits dull. Source: gamegrin.com, steamcommunity.com.
Camera and movement never fight the player
The large world map can be zoomed in on provinces and viewed in layers for politics, trade and religion, though early players noted the zoom level resets after loading a save. Source: ign.com, boards.straightdope.com.
