Compare Prices(3 stores)
Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.
Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.
We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.

About Europa Universalis III: Heir to the Throne (DLC)
Grand strategy asks for patience before it pays out, and this expansion asks for a specific kind: you need Europa Universalis III Complete on your account for it to load at all, so verify that first. What Heir to the Throne actually adds is the dynastic layer. Personal unions and royal marriages become tools instead of flavour text, Casus Belli get reworked so wars have stated aims and matching peace terms, and the Holy Roman Empire gets an internal politics system with imperial authority, princes, and reform votes worth gaming. There is also a mission and decision framework that gives smaller nations something to aim at. For anyone still running EU3 rather than IV, this is the layer that makes the diplomatic mid-game interesting, and the HRE changes alone justify a Central European campaign. Skip it if you only own the base game or a partial bundle, since it will not activate. Check the store listing for the full feature breakdown.
